  • Highly luminescent hierarchical architectures of lanthanide-based
           complexes
    • Abstract: Publication date: Available online 23 March 2019Source: Inorganic Chemistry CommunicationsAuthor(s): Nijuan Liu Novel luminescent metallogelators have been successfully prepared by cationic surfactant (DODA, DODA = dimethyl dioctadecyl ammonium) and lanthanide complexes [Ln(dpa)3]3− (Ln = Eu, Tb; dpa = pyridine-2,6-dicarboxylate), and their hierarchical self-assembly behaviors are also investigated. TEM and SEM results indicate that they can self-assemble into highly luminescent flower-like and giant vesicular architectures in organic solvents, respectively. The present concept suggests that the combination of lanthanide(III) complexes with stepwise molecular self-assembly will open an alternative methodology to develop lanthanide(III)-based sensory and optoelectronic materials.Graphical abstractThe electrostatic incorporation of [Ln(dpa)3]3− anions (Ln = Eu, Tb) into cationic surfactant matrices leads to the formation of lanthanide-based metallogels in dodecane. Upon evaporating the solvent, the xerogels self-assemble into highly luminescent flower-like and giant vesicular architectures.Unlabelled Image
       
  • Synthesis, crystal structure and properties of a 2D hexa-nuclear ring
           Cu/Na-substituted sandwich-type arsenotungstate
    • Abstract: Publication date: Available online 23 March 2019Source: Inorganic Chemistry CommunicationsAuthor(s): Xiujuan Ma, Zhanhua Su, Zhifeng Zhao, Baibin Zhou, Kai Yu, Yongchen Shang, Meijia Wang, Yunyan Tian One hexa-nuclear ring Cu/Na-substituted sandwich-type arsenotungstate, [Cu(Himi)4][(pz)0.5{Cu3Na3(AsW9O33)2}](Hpz)3·H2O (1), (pz = pyrazine, imi = imidazole) has been synthesized and structurally characterized. Basic frameworks of 1 is constructed from sandwich-type [(pz)0.5{Cu3Na3(AsW9O33)2}] anions, [Cu(Himi)4] complex, free protonated pz ligands and water molecule. The transition metal ions Cu2+ and Na+ in the central belt connect alternately in an edge-sharing mode forming a hexa-nuclear ring. Pz ligand and [Cu(Himi)4] as bridge connect to {Cu3Na3(AsW9O33)2} fragments, respectively, which forms a enormous ten-members ring, then leading to constitute a novel 2D ABAB arrangement layer structure. The pz as bridge to link two hexa-nuclear ring Cu/Na-substituted sandwich-type arsenotungstates is first observed. Additionally, compound 1 shows excellent photocatalytic activity for the degradation of MB and RhB dye under UV irradiation. The photocatalytic reaction mechanism has been also investigated. In addition, the electrochemical and electrocatalytic activity upon the reduction of H2O2 also has been studied.Graphical abstractUnlabelled Image
       
  • Synthesis and photocatalytic properties of two different chitosan-based
           structural hydrogenase models
    • Abstract: Publication date: Available online 22 March 2019Source: Inorganic Chemistry CommunicationsAuthor(s): Meng Cao, Zhenxi Wang, Zuocheng Yuan, Xinde Jiang, Sheng Xu, Yang Liu, Shangxi Zhang, Xin Dai Chitosan derivatives containing phosphorus ligands were successfully synthesized in three steps. Depending on the degree of substitution, these derivatives present different states, namely colloidal 1 (16.31%) and powdery 1a (92.99%). Based on this, two kinds of diiron model compounds with different morphologies (2 and 2a) were synthesized. The intermediates (1, 1a) and final products (2, 2a) were characterized by SEM (EDX), EA, FT-IR, XRD and TG-DTA. As new multiphase catalysts, 2 and 2a have been applied to photocatalytic reactions. Under optimum conditions ([Ru(bpy)3]Cl2.6H2O, DMF/H2O/TEA, v/v/v = 8/1/1), the turnover numbers were 35 (2) and 24 (2a) for catalysts in an hour of illumination. In addition, a possible photocatalytic mechanism was proposed.Graphical abstractUnlabelled Image
       
  • Hydrogen storage capacities of some new Hg(II) complexes containing
           2-acetylethiophene
    • Abstract: Publication date: Available online 19 March 2019Source: Inorganic Chemistry CommunicationsAuthor(s): Ban Dawood Salih, Mustafa A. Alheety, Ahmed Raoof Mahmood, Ahmet Karadag, Dhekra Jawad Hashim Novel mercury divalent ion complexes with 2-acetylethiophene (AcT) were synthesized. The treatment of HgCl2 with AcT in ethanol at room temperature in 1:1 and 1:2 mercury to AcT ratios affords [Hg(AcT)Cl2] (1) and [Hg(AcT)2]Cl2 (2) respectively. Both complexes (1) and (2) were used as synthone for preparation the complexes of the type [Hg(AcT)(L-L)]Cl2 where the bidentate ligands were either aliphatic amines L-L; ethylenediamine (en) (3), N-methylethylenediamine (Men) (4), N-ethylethylene-diamine (Een) (5) and 1,3-diaminopropane (Dap) (6) or heterocyclic amines L-L; 2,2′-bipyridine (bipy) (7) and 1,10-phenanathroline (phen) (8). When complex (1) was used, the resulted complexes of the type [Hg(AcT)(L-L)]Cl2 were pure. Column chromatography packed with silica was used to separate the resulted complexes in pure form when complex (2) was used as a starting material. Furthermore, the treatment of complex (1) with two moles of triphenylephosphine (PPh3) results in the mixture of [Hg(AcT)(PPh3)2]Cl2 (9) and [Hg(AcT)(O = PPh3)2]Cl2 (10). These two complexes were separated using sephadex column depending on their molecular weight. The prepared complexes were characterized by molar conductivity, FT-IR, 1H-, DEPT 13C-{1H}, 31P-{1H}NMR and elemental analyses. The characterization results show that AcT behaves as a chelate bi-dentate ligand through sulfur and oxygen atoms in all complexes. The prepared complexes were characterized to be tetrahedral complexes. In order to take benefit of the prepared complexes, (1), (8) and (9) were selected to test their surface areas and hydrogen storage abilities. In addition, the thermodynamic properties of H2 adsorption (enthalpy and entropy) were determined at four different temperatures using the Clausius Clapeyron equation. The results prove that the prepared complexes were capable of storing the hydrogen.Graphical abstractUnlabelled Image
       
  • Supercapacitive performance of highly dispersed bismuth sulfide
           nanoparticles in organic matrix: The role of sulphur source
    • Abstract: Publication date: Available online 18 March 2019Source: Inorganic Chemistry CommunicationsAuthor(s): Nishu Devi, Sarit Ghosh, Kaushik Mallick Ultra-fine, highly dispersed bismuth sulfide nanoparticles have been synthesized, using two different sulphur sources (sodium sulfide and thiourea) by applying a wet chemical method. The bismuth sulfide (BST) nanoparticles synthesized using thiourea, as a sulphur source, displayed higher crystallinity than the bismuth sulfide (BSS) produced with sodium sulfide. Both the materials have been tested as an electrode material for supercapacitor applications via electrochemical studies (cyclic-voltammetry and galvanometric charge-discharge techniques) in presence of alkaline electrolyte. The BSS and BST based electrodes exhibited maximum specific capacitance values of 250 F.g−1 and 491 F.g−1, respectively, at the current density of 0.5 A.g−1. Both the materials achieved the energy density values>40 Wh.kg−1 at the current density of 0.5 A.g−1. The present work demonstrates a simple synthesis method for the fabrication of highly dispersed organic molecule stabilized bismuth sulfide nanoparticles for supercapacitor application.Graphical abstractUnlabelled Image
       
  • Effect of oleic acid content on manganese-zinc ferrite properties
    • Abstract: Publication date: Available online 16 March 2019Source: Inorganic Chemistry CommunicationsAuthor(s): Taweesak Kaewmanee, Surangkana Wannapop, Anukorn Phuruangrat, Titipun Thongtem, Orawan Wiranwetchayan, Wonchai Promnopas, Sakon Sansongsiri, Somchai Thongtem One step hydrothermal synthesis of Mn-Zn ferrite was processed using different contents of ionic manganese, ionic zinc and oleic acid as an anti-agglomeration.

    • Abstract: Publication date: Available online 16 March 2019Source: Inorganic Chemistry CommunicationsAuthor(s): Abebe G. Habte, Fekadu Gashaw Hone, F.B. Dejene Cadmium Selenide thin films were deposited on glass substrates by chemical bath deposition technique. The films have been characterized by using X-ray diffraction (XRD), UV–Vis spectroscopy, scanning electron microscopy (SEM), photoluminescence spectroscopy. The XRD study showed that the obtained thin films were CdSe with cubic crystal structure. The average crystallite size of 4.13–5.14 nm was obtained with different concentration of malonic acid. The relative intensities of the prominent diffraction peaks decreased with increasing concentration of malonic acid. The SEM images confirmed that there were considerable changes in the morphology of CdSe nanoparticles with the molar concentrations of malonic acid. The optical band gaps of the nanoparticle were estimated from the UV–Vis spectroscopy measurement and obtained in the range of 2.03 eV to 1.74 eV. The photoluminescence spectra showed a well-defined peak at 543 nm and shoulders around 487 nm and 530 nm for all CdSe thin films.

  • A novel Pb2+-selective micellar self-assembled fluorescent chemosensor
           based on amino thiadiazole calix[4]arene derivative
    • Abstract: Publication date: May 2019Source: Inorganic Chemistry Communications, Volume 103Author(s): Zi-hao Guo, Yuan-yi Li, Cai-ping Ding, Xiao-jun Hu, Yan Wen, Bo Wang A novel “turn-off” micellar self-assembled fluorescent chemosensor for detecting Pb2+ ions based on calix[4]arene derivative was prepared through self-assembly of amino thiadiazole calix[4]arene derivative (AMT-CA) as receptor, pyrene as fluorophore and trimethyltetradecylammonium bromide (TTAB) as template in aqueous solution. The fluorescence of pyrene was quenched by Pb2+ ions owing to the close proximity of the AMT-CA-Pb2+ complex to the pyrene based on fluorescent internal filter effect (IFE). The effects of pH value, concentration of TTAB and pyrene, molar ratio of AMT-CA/pyrene on the fluorescent chemosensor were studied. Further, the linear response for Pb2+ ions was in the range of 2–52 μmol/L. And Pb2+ ions can be selectively detected in the presence of cations (Ca2+, Mg2+, K+, Na+, Al3+, Zn2+, Ba2+, Cd2+) and anions (CH3COO−, Br−, Cl−, SO42−, NO3−). Other similar micellar self-assembled fluorescent chemosensor with selective detection for other ions will be researched and developed based on calix[4]arene.Graphical abstractUnlabelled Image
       
  • Itinerant ferromagnetism induced by electron doping in
           SrCo2As2
    • Abstract: Publication date: May 2019Source: Inorganic Chemistry Communications, Volume 103Author(s): Shijie Shen, Wenwu Zhong, Dandan Li, Zhiping Lin, Zongpeng Wang, Xinxin Gu, Shangshen Feng It is a fascinating question whether it exists and how to explore Co-based high-temperature superconductors, since Co is next to Fe and has just one more electron than Fe. Based on this, SrCo2As2 has attracted great research interest due to its similar magnetic ground state to Fe-based superconductors. Here, we studied the electron doping effect of SrCo2As2 by doping 2.5% Nd at the Sr sites. Our experimental results show that injecting electrons caused by this doping can induce it from paramagnetism to ferromagnetism. The first-principles calculation indicates that the density of states at the Fermi surface is high enough, which tends to be related to ferromagnetism. This work provides a general strategy for inducing ferromagnetism in Stoner paramagnetic systems.Graphical abstractUnlabelled Image

Comparing with the control devices, devices based on af-MWNTs HLTs achieved an optimal power conversion efficiency (PCE) of 6.970%, leading to 17.6% enhancement comparing to the control device. The af-MWNTs HTLs exhibited remarkable enhancement on electrical conductivity, which was beneficial to the hole extraction and transport on interface. The enhancement of PCE was mainly attributed to the superior hole transport and extraction capabilities. Meanwhile, the af-MWNTs exhibited a suitable work function (WF) which was beneficial to hole extraction from the photoactive layer to the ITO anode. The experimental results indicated that the af-MWNTs HTLs not only presented excellent optical and electrical properties, but also played an important role for improving the efficiency of PSCs.Graphical abstractUnlabelled Image

    • Abstract: Publication date: Available online 23 February 2019Source: Inorganic Chemistry CommunicationsAuthor(s): Xiaojun Luo, Zhicai Mai, Hao Lei A new 3D metal-organic framework (PMI)2[Zn4(μ4-O)Br2L2] (1, PMI = 1-propyl-3-methylimidazolium, H3L = biphenyl-3,4′,5-tricarboxylic acid) was prepared from tricarboxylic acid H3L and Zn(NO3)2 under ionothermal conditions. Single crystal X-ray diffraction analysis reveals that the anionic framework possesses a (3,6)-connected topological network and contains rare {Zn4(μ4-O)Br2} clusters as building units. The compound was further characterized by powder X-ray diffraction (PXRD), Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA). Interestingly, 1 can serve as a sensitive and recyclable luminescent probe to detect Fe3+ ions. In addition, 1 can effectively and selectively absorb cationic dyes, possibly due to the anionic nature of the framework.Graphical abstractUnlabelled Image

  • Novel MIL-88A/g-C3N4 nanocomposites: Fabrication, characterization and
           application as a photocatalyst
    • Abstract: Publication date: Available online 22 February 2019Source: Inorganic Chemistry CommunicationsAuthor(s): S. Gholizadeh Khasevani, M.R. Gholami The nanocomposite of g-C3N4 supported by MIL-88A has been prepared via a facile hydrothermal method. The photocatalytic performance of as-prepared composite (MIL-88A/g-C3N4) was examined by the degradation of the Methylene Blue (MB) solution under visible light. The characterization test illustrated that the MIL-88A particles were successfully dispersed on the surface of g-C3N4 structure. Photoactivity results demonstrated that the MIL-88A/g-C3N4/H2O2 exhibited dramatically visible light photocatalytic performance. Hydroxyl radicals (OH) are generated by dissociation of H2O2 under visible irradiation can remarkably enhance the degradation rate of MB molecules. Meanwhile, the studies of catalytic activity indicated that the conductive properties of MIL-88A/g-C3N4 with the structure as well as ROS species formation simultaneously lead to the enhanced photoactivity of MIL-88A/g-C3N4 composite. Furthermore, OH and O2– radicals species played the essential role for photodegradation MB dye.Graphical abstractUnlabelled Image

The single crystal X-ray study reveals that compound 1 is built up from the {Cu3(ma)(COO)6(H2O)2} cluster-based secondary building unit (SBU) and incorporates two types of polyhedral cages in the framework, which results in 1D nanosized channels along the c axis. More importantly, the activated compound 1 exhibits not only high uptake capacity for CO2 molecules at room temperature but also a significant selective adsorption of CO2 over CH4, which may be ascribed to the proper-sized pores with high density of open metal sites as well as the amine and triazine decorated pore surroundings. Meanwhile, the Grand Canonical Monte Carlo (GCMC) simulations on CO2 adsorption of compound 1 demonstrate that the both of the open metal sites and melamine backbone play key roles in the CO2 binding.Graphical abstractA new cluster-based microporous metal-organic framework containing open metal sites and uncoordinated nitrogen atoms on the internal surface was solvothermally synthesized.

It has been found the antibacterial activity and bioavailability of nano–sized ciprofloxacin hydrochloride can be largely improved. In this study, we demonstrate the bacteriostasis rate of ciprofloxacin hydrochloride was nearly doubled through the formation of nanomedicines. To this end, a facile solvent–assisted mechanochemical synthetic pathway was proposed to fabricate diprofloxacin hydrochloride nanomedicine (nano–CIP), which was further evaluated for the antibacterial activity against Escherichia coli (E. coli). Results showed that the bacteriostasis rate of nano–CIP reached ca. 86.4% which was nearly 2–fold that of ciprofloxacin hydrochloride powder (44.2%). At the same time, antibacterial plate experiments revealed significantly superior antibacterial effect of nano–CIP than the CIP precursors, which was largely due to the increased contact areas at surfaces of nanomedicines. Overall, this work presented a facile and effective means to prepared nanomedicines with enhanced bacteriostasis effects and bioavailability, which were key for practical applications in medicinal areas.Graphical abstractCiprofloxacin nanomedicines were prepared through the solvent–assisted mechanochemical method and exhibited enhanced antimicrobial activity against Escherichia coli.Unlabelled Image

In this work, oxygen vacancies were introduced into In2O3 nanocubes via hydrogenation. The formation of oxygen vacancies was verified by a variety of characterization techniques. Compared to the pristine In2O3 nanocubes, the hydrogenated In2O3 nanocubes exhibited substantially higher photoelectrochemical performance. The enhanced photoelectrochemical performance of hydrogenated In2O3 nanocubes could be attributed to the increased optical absorption, more donor density and the efficient charge transfer and separation of photo-induced charge carrier derived from oxygen vacancies.Graphical abstractUnlabelled Image

    • Abstract: Publication date: Available online 4 February 2019Source: Inorganic Chemistry CommunicationsAuthor(s): Faiz-Ur Rahman, Amjad Ali, Inam Ullah Khan, Muhammad Zeeshan Bhatti, Manuel Petroselli, Hong-Quan Duong, Javier Martì-Rujas, Zhan-Ting Li, Hui Wang, Dan-Wei Zhang Two new monofunctional mono-metallic trans-Pt(II)(salicylaldimine)(pyridine)·BF4 (C1) and supramolecular dimetallic trans-(Pt(II)(salicylaldimine))2(4,4-bipyridine)·2BF4 (C2) complexes were designed and synthesized through ancillary chloride ligand exchange strategy and structurally characterized by spectroscopic, spectrophotometric and single crystal X-ray analyses. The solid-state structure analyses revealed interactions between the coordination planes, inter-molecular H-bonding, bonding in the ligand hydrogen and BF4 anions and supramolecular interactions with solvent molecules in crystal packing. The in vitro anticancer effect of these complexes was investigated in breast (MCF-7) and liver (HepG2) cancer cells. Both these complexes showed significant anticancer effect comparable to cisplatin. Similarly, the effect of these complexes on Escherichia coli (E. coli) growth retardation was also analyzed and the results revealed stronger growth retardation effects and elongated morphology of bacterial cells in similar fashion as observed for cisplatin. The DNA interaction of C1 and C2 was investigated by gel electrophoresis using pET28 as target DNA. These complexes retarded migration of DNA across the gel showing their interaction with DNA.Graphical abstractUnlabelled Image
       
  • Thermodynamic computational calculations for preparation
           5-fluorouracilmagnetic moleculary imprinted polymers and their application
           in controlled drug release
    • Abstract: Publication date: Available online 4 February 2019Source: Inorganic Chemistry CommunicationsAuthor(s): Laleh Talavat, Ali Güner The interaction dynamics between drug-monomer-solvent is the backbone of the thermodynamic calculation in molecular imprinting process and the controlled drug release components. In this regards, thermodynamic computational calculation was used for preparation of magnetic molecular imprinted polymers (MMIPs) and their subsequent application in the controlled release of 5-fluorouracil in the cancer therapy. Cohesive energy density of components (CED)/resolution parameters (δd, δp, δH) are the important characteristic of desired profile and design. Accordingly, the calculations for choosing the best reactants were performed based on the utilization of chemical affinity profiles of Hansen method. Based on the thermodynamic computational calculations, 4-vinylpyridine (4-VP) and acrylic acid (AA) were chosen as optimal monomers to synthesize MMIPs. MMIPs were utilized as the pH responsive nanocarrier systems in the controlled release of 5-fluorouracil (5-FU) as an anti-cancer drug. At first, the Fe3O4 nanoparticles were functionalized by vinyl triethoxysilane moieties and finally, a MIP layer was synthesized on the surface of modified magnetic nanoparticles via precipitation polymerization process. The prepared polymer was characterized by FT-IR spectroscopy, scanning electron microscopy, thermogravimetric analysis (TGA), differential scanning calorimetric analysis (DSC), elemental analysis, and X-ray diffraction analysis. The results of high performance liquid chromatography analysis illustrated the controllable release of 5-FUin simulated body fluid at pH = 5.8 and pH = 7.4. At the end of 30 day, 90% and 80% of 5-FU released at pH 5.8 from 5-FU/4-VP and 5-FU/AA MMIPs, respectively, while these values at pH 7.4 were 70% and 65%, for 5-FU/4-VP and 5-FU/AA MMIPs, respectively. The preparation of these MMIPs was facile and fast and they are biocompatible.Graphical abstractUnlabelled Image
       
  • ZnIn2S4/UiO-66-(SH)2 composites as efficient visible-light photocatalyst
           for RhB degradation
    • Abstract: Publication date: Available online 4 February 2019Source: Inorganic Chemistry CommunicationsAuthor(s): Jinxi Chen, Fufang Chao, Xixi Mu, Jifei Jiang, Qiong Zhu, Jiaojiao Ren, Yu Guo, Yongbing Lou A series of composites of ZnIn2S4 and UiO-66-(SH)2 denoted as ZIS/US have been successfully prepared by simple solvothermal method. The results of photocatalytic degradation for RhB experiments showed that the photocatalytic activities of the composites were higher than that of both single materials. With a dosage of only 5 mg ZIS/US-20 (the amount of UiO-66-(SH)2 in preparation was 20 mg), the degradation rate was high as 96% after 60 minute visible-light irradiation. The possible photocatalytic mechanism of the ZIS/US composites was also explicated. The enhanced photocatalytic activity of the complex was mainly attributable to the efficient electrons separation between ZnIn2S4 and UiO-66-(SH)2, and the composites also owned the ability to produce more active species (OH, O2−). The ZIS/US composites provided an innovative candidate in organics removal.Graphical abstractUnlabelled Image
       
  • Colorimetric sensor for real-time detection of cyanide ion in water and
           food samples
    • Abstract: Publication date: Available online 3 February 2019Source: Inorganic Chemistry CommunicationsAuthor(s): R. Bhaskar, S. Sarveswari An unreported organic probe (A1) was rationally designed and synthesized. The structural characterization of the A1 has been examined using NMR, FT-IR, ESI-MS and UV–Vis spectral techniques. The A1 dispensed high sensitivity and improved selectivity towards the cyanide ion in aqueous media, which was evidenced from the drastic color change. The detection limit of A1 was found to be 1.95 × 10−7 M which appreciably competes with existing CN− probes. The binding mechanism of the probe with cyanide ion was confirmed through 1H NMR titration method. Furthermore, A1 will be efficiently used to detect trace amount of cyanide ion present in food samples such as cassava flour, apple seeds, and sporting potatoes.Graphical abstractUnlabelled Image

  • Spectroscopic investigations of the interactions of potential antitumor
           amino-thiazolidinone platinum (II) compounds with human serum albumin
    • Abstract: Publication date: Available online 2 February 2019Source: Inorganic Chemistry CommunicationsAuthor(s): Jia Shao, Jin-Xia Wei, Yi Zhang, Jing-Yuan Xu An amino-thiazolidinone platinum(II) compound which could rapidly induce apoptosis in tumor cells and showed no cross resistance against the cisplatin-resistant cells, was firstly to study of protein-drug interactions. To investigate the potential of Pt(II) compounds as therapeutic drugs, two Pt(II) complexes (1 and 2) were explored the influences based on their interaction in vitro with human serum albumin (HSA) by fluorescence spectrometry and UV–Vis absorption. The binding interactions of two compounds with HSA results in the formation of corresponding HSA-drug complexes, van der Waals forces and hydrogen bonding played key roles in stabilizing these complexes. Both of two compounds were through a dynamic quenching mechanism, this dynamic reversible binding process was of great significance to the equilibrium of drug concentrations in vivo, which ensured that the internal environment of the organism was in a relatively stable state.Graphical abstractUnlabelled Image
       
  • New ternary platinum(II) dithiocarbamates: Synthesis characterization,
           anticancer, DNA binding and DNA denaturing studies
    • Abstract: Publication date: Available online 2 February 2019Source: Inorganic Chemistry CommunicationsAuthor(s): Muhammad Imran, Zia-ur-Rehman, Tamara Kondratyuk, Francine Bélanger-Gariepy Two new ternary platinum(II) complexes of general formula [Pt(DTC)LCl], where DTC = 4-(2-pyridyl)piperazine-1-carbodithioate (1 and 2) and L = tri(p-tolyl)phosphine (1) and tri(o-tolyl)phosphine (2), have been synthesized and characterized. Both complexes have shown phenanthriplatin and picoplatin type axial protection, albeit from both sides, offered by CH moiety of the organophosphine (X-ray single crystal and DFT analysis). Furthermore, 2 has shown greater degree of axial shielding of platinum center than 1. In vitro anticancer activity against three cancer cell lines has revealed greater anticancer potency of 2 than 1. The activity against NF-κB (a cancer promoting protein) signified that death of the cancer cells may be due to hindering the activity of NF-κB and subsequent initiation of the apoptosis. High activity of 2 than 1 can be attributed to its greater lipophilicity and stronger axial protection (CH⋯Pt = 2.752 Å, HC⋯Pt 3.496 Å, ∠H⋯Pt-P = 78.37° and ∠ C⋯Pt-P = 64.19°), from both sides of the axial plane, that may hinder the diversion to off target biomolecules and thus may enhance cellular uptake. Based upon DNA binding and DNA denaturing studies with CT-DNA, a cooperative binding and non-intercalative (electrostatic) mode of interaction have been suggested.Graphical abstractUnlabelled Image

  • A new inorganic sealing material used for gas extraction borehole
    • Abstract: Publication date: Available online 31 January 2019Source: Inorganic Chemistry CommunicationsAuthor(s): Aitao Zhou, Kai Wang The quality of borehole sealing has significant influence on the gas extraction. Inorganic sealing material has the advantages of low cost, multiple functions and high performance; therefore, it has been widely used in many fields. In the paper, the single factor experiment was conducted on the new inorganic sealing material, and the effect of the polymer and the expansive agent on the properties of the new inorganic seal material was studied, on the basis of which such three factors as polymer-to-cement weight ratio, dosage of dispersant, and dosage of the expansive were used as the research object of the orthogonal experiment; the flexural strength, compressive strength and expansion coefficient were used as the evaluation indicators to analyze the effect of such three factors on the properties of the inorganic material. The results of the research show that the final proportion of the new inorganic sealing material is: 1.2% dosage of dispersant, 6% polymer-to-cement weight ratio, and 0.1% dosage of expansion agent. The water cement ratio exerts great influence on the mechanical properties of the material; the higher the water cement ratio is, the lower the compressive strength and the flexural strength are. Furthermore, the water cement ratio also has significant influence on the fluidity of the slurry; the water cement ratio is determined to be 1.5:1. According to the aforesaid proportion, the sealing performance test was conducted on the new inorganic sealing material, and the comparison was made with the Portland cement material. The results of the test show that the time required for the air space to restore from the initial pressure value to the atmospheric pressure value is much greater than that needed for the cement material, so the sealing performance of the inorganic sealing material is much better than that of the Portland cement materials. It is of practical significance to develop the new inorganic seal material, which can improve the quality of sealing, increase the gas extraction rate and reduce the mine gas accidents.Graphical abstractThe inorganic sealing material has the advantages of low cost, multiple functions and high performance, so it has been widely used in many fields.

Cheng, Gregory S. Smith, Kirkwood M. Land Clinical cases of metronidazole resistant Trichomonas vaginalis infections have spurred interest in drug discovery against this protozoal parasite. We have carried out a structure-activity studies using mononuclear palladium(II) complexes containing salicylaldiminato thiosemicarbazones on a patient isolate of Trichomonas vaginalis highly resistant to the FDA-approved drug metronidazole. A small library of sixteen compounds were analysed on this resistant isolate. Interestingly, compared with our previous analysis of a metronidazole sensitive strain, susceptibility of this resistant isolate to four of the six most potent compounds was observed. Two compounds had similar IC50 values between the resistant strain and a previously analysed sensitive line. Palladium(II) salicylaldiminato thiosemicarbazone complexes may represent, with further development, a new drug discovery direction for treating clinical cases of metronidazole-resistant T. vaginalis. The most potent compound had an IC50 value of 15 μM on parasite growth and showed no effects on common normal flora bacteria and no morphological effects when tested on cultured mammalian cells.Graphical abstractUnlabelled Image
       
  • Reversible CO2 capture/release of sodium manganate with a layered
           structure in the presence of water vapor at 25–150 °C
    • Abstract: Publication date: Available online 24 January 2019Source: Inorganic Chemistry CommunicationsAuthor(s): Ikuo Yanase, Takano Takuya Sodium manganates with a layered structure, Na0.7MnO2.05, have been applied to a novel material for CCUS (CO2 capture, utilization, and storage), capable of capturing CO2 at 25 °C in the presence of water vapor and releasing CO2 at 150 °C. The temperatures of capturing and releasing CO2 of Na0.7MnO2.05 were remarkably lower than those of other traditional metal oxides. The CO2 absorption and desorption properties of Na0.7MnO2.05 were investigated by various methods, such as thermogravimetry, Fourier transform infrared spectroscopy, X-ray diffractometry, and gas chromatography. These investigations confirmed that Na0.7MnO2.05 absorbed CO2 at 25 °C in the presence of water vapor to produce NaHCO3 and a birnessite and the CO2 absorption was promoted by increasing relative humidity and CO2 concentration. The CO2 absorption at 25 °C of Na0.7MnO2.05 was promoted by the formation of a strong basic solution on Na0.7MnO2.05, caused by the elution of Na ions from the interlayer of Na0.7MnO2.05 into water, adsorbed on the Na0.7MnO2.05 surface. Furthermore, Na0.7MnO2.05 was regenerated by heating the CO2-absorbed Na0.7MnO2.05 at temperatures as low as 150 °C. The low-temperature regeneration indicates that Na0.7MnO2.05 can be a low-energy consumption material for capturing and releasing CO2 at low temperatures.Graphical abstractUnlabelled Image

  • Effects of substituent groups on the crystal structures and luminescence
           properties of zero-/two-dimensional Zn(II) complexes
    • Abstract: Publication date: Available online 15 January 2019Source: Inorganic Chemistry CommunicationsAuthor(s): Bin Li, Zhi-Qiang Xu, Ying-Bo Xu, Guo-Ping Yong The 3-position substituted imidazo[1,2-a]pyridine ligands L1 and HL2 were facilely synthesized, and used for construction of two novel luminescent Zn(II) complexes, namely [ZnCl2(L1)2] (1) and [Zn(L2)2]n (2). Single-crystal X-ray diffraction analysis shows that 1 is zero-dimensional structure, whereas, 2 possesses two-dimensional polymeric network with rhombic grid motifs. The structural differences between 1 and 2 should be determined by the different substituent groups adjacent to carbonyl groups of the 3-position substituted imidazo[1,2-a]pyridine ligands. Complex 1 reveals the red-shifted emission band, compared to free L1 ligand, whereas, 2 displays similar emission spectrum to free HL2 ligand. Such results are also ascribed to substituent group effects and corresponding structural differences.Graphical abstractUnlabelled Image
