  • Development of highly selective chemosensor for chomium(III) estimation in
           aqueous environment
    • Abstract: Publication date: Available online 16 January 2019Source: Inorganic Chemistry CommunicationsAuthor(s): V. Raju, R. Selva Kumar, S.K. Ashok Kumar, Y. Tharakeswar, Suban K. Sahoo A new antipyrine Schiff's base, 2-((2,5-dimethyl-3-oxo-1-phenyl-2,3-dihydro-1H-pyrazol-4-yl)imino)-1H-indene-1,3(2H)-dione (L) has been synthesized by simple condensation of ninhydrin with 4-aminoantipyrine. The sensing ability of L was studied with selected metal ions from s-block and d-block elements by visual and UV–Vis spectrometry in water: methanol (8:2, v/v) media. The naked-eye detectable colour change of L was occurred from pink to colourless upon interacting with Cr3+ while other metal ions did not change the colour of L. The two main absorption bands appeared at 425 nm and 540 nm of L were quenched upon interaction with Cr3+ while other tested metal ions failed to perturb the absorption bands of L. The Jobs plot and UV–visible spectral studies indicate the formation of a 2:1 complex between the L and Cr3+ with an association constant of 3.0 × 104 M−1. The limit of detection (LOD) of L for the analysis of Cr3+ found to be 5.4 × 10−7 M. The CrL2 complex formation in solution is reversed after treatment with ethylenediaminetetracetic acid (EDTA). The colorimetric sensing ability of Schiff's base L was successfully utilized in the preparation of test paper strips and solid supported silica for the real samples analysis to detect Cr3+ ions from 100% aqueous environment.Graphical abstractUnlabelled Image
       
  • Two efficient near-infrared (NIR) luminescent
           [Ir(C^N)2(N^O)]-characteristic complexes with 8-hydroxyquinoline (8-Hq) as
           the ancillary ligand
    • Abstract: Publication date: Available online 15 January 2019Source: Inorganic Chemistry CommunicationsAuthor(s): Jiahao Guo, Jin Zhou, Guorui, Yani He, Wentao Li, Xingqiang Lü Through the utilization of Hiqbt (1-(benzo[b]-thiophen-2-yl)-isoquinoline) or Hdpbq (2,3-diphenyl benzo[g]quinoxaline) as the C^N main ligand and 8-Hq (8-hydroxyquinoline) as the N^O ancillary ligand, two [Ir(C^N)2(N^O)]-characterized heteroleptic complexes [Ir(iqbt)2(8-q)] (1) and [Ir(dbpq)2(8-q)] (2) with desirable soluble and NIR-phosphorescent properties (λem = 687 nm with a shoulder at 756 nm, lifetime τ = 0.73 μs and quantum efficiency Φem = 0.16 for complex 1versus λem = 786 nm, lifetime τ = 0.47 μs and quantum efficiency Φem = 0.05 for complex 2) are obtained, respectively. In comparison, the distinctive bathochromatic shift into a typical NIR region of complex 2, arisen from the large-molecule-conjugation-induced narrow energy gap, gives rise to its relatively lower quantum efficiency than that of complex 1.Graphical abstractReplaced by the large π-conjugation-induced C^N ligand Hdpbq, the distinctive bathochromatic shift into a typical NIR region (λem = 786 nm) for [Ir(dpbq)2(8-q)] (2) relative to that (λem = 687 nm with a shoulder at 756 nm) of [Ir(iqbt)2(8-q)] (1) while relatively lower quantum efficiency Φem = 0.16 versus Φem = 0.05 are observed.Unlabelled Image
       
  • The effect of coordination habits of metal ions on fabricating
           metal-organic frameworks with thiophenedicarboxylate
    • Abstract: Publication date: Available online 15 January 2019Source: Inorganic Chemistry CommunicationsAuthor(s): Hong-bo Yuan, Li Fu, Li-jiao Chen, Bao Li Two new Metal-Organic Frameworks, [Zn3(tdc)3(H2O)2]·2.5(dioxane) (1) and [Mn3(H2O)3(tdc)3(dioxane)]·2(dioxane) (2), have been successfully constructed by the utilization of 2,5-thiophenedicarboxylate ligand (H2L) and Zn/Mn ions. Although trinuclear metal secondary building units (SBUs) have been stabilized in these two final frameworks, the different connection modes are exhibited due to the difference of coordination habits of metal ions. The trinuclear [Zn3(COO)6] SBU exhibits the 6-connected mode via six L ligands, whilst the trinuclear [Mn3(COO)6] SBU presents the 8-connected mode via six L ligands and two p-dioxane molecules. The different connection modes of two trinuclear SBUs lead to the formation of distinct topological structures (6-connected pcu for 1; 8-connected tsi for 2). Both of the activated samples for these two MOFs could reserve the certain porosities and exhibit the corresponding gas sorption for H2.Graphical abstractTwo Metal-Organic Frameworks have been successfully constructed under the similar reaction condition, and the coordination habits of metal ion are responsible for the difference of final structure.Unlabelled 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
       
  • CeO2 quantum dots modified electrode for detecting hydrogen
           peroxide
    • Abstract: Publication date: Available online 15 January 2019Source: Inorganic Chemistry CommunicationsAuthor(s): Yaping Wang, Junchao Qian, Zhigang Chen, Chencheng Wang, Chengbao Liu, Yue Yang, Zhiyi Wu, Yenan Song This study describes the fabrication of a sensitive modified electrode for detecting hydrogen peroxide. The glassy carbon surface was modified with a composite containing CeO2 quantum dots and carbon sheets. The ultra-small grain size of nanoparticle endows the electrode with excellent electrocatalytic activity. As a result, the electrode shows electrocatalytic reduction activity toward H2O2 at a potential of −0.5 V. The CeO2 quantum dots sensor shows a satisfactory performance for detecting hydrogen peroxide with a linear range of 2 ppm–1000 ppm, and a limit of detection (LOD) of 900 ppb. These findings show that CeO2 quantum dots have a great potential for applications in electrochemical sensing.Graphical abstractUnlabelled Image

  • A Zn(II)/anthracene coordination polymer showing highly efficient
           photocatalytic Cr(VI) reduction in aqueous solution
    • Abstract: Publication date: Available online 11 January 2019Source: Inorganic Chemistry CommunicationsAuthor(s): Jing Li, Wei Gou, Yan Zhou, Zhen-Fang Lin, Fei Peng Reaction of Zn(OAc)2·2H2O with the visible light responsive organic ligand 9,10-bis(4′ -pyridylethynyl)-anthracene (BPEA) gave rise to a Zn(II)/anthracene coordination polymer [Zn(OAc)2(BPEA)]n.

The isolated complex 2 was further reacted with an excess of PTA ligand in a 9:1 ratio of water and methanol to yield the highly soluble cis-trans-[Re(Acac)(CO)2(PTA)2] (3). The complexes have been characterized by spectroscopic techniques IR, 1H, 13C and 31P NMR, as well as single crystal X-ray crystallography for 2 and 3. From the crystallographic results of 3, the formation of the cis-trans conformation was confirmed, while the 31P NMR results further established 3 as the sole product formed.

The as-prepared samples were characterized by X-ray diffraction (XRD), high resolution transmission electron microscopy (HRTEM), laser Raman Spectroscopy (LRS), X-ray photoelectron spectroscopy (XPS), UV–vis diffuse reflection spectroscopy (UV–Vis DRS) and N2 adsorption-desorption measurements. The adsorption and photocatalytic properties of the as-prepared samples were evaluated using ethyl mercaptan (EM) in methane gas as the model pollutant. The results indicated that CeO2-NPs were uniformly distributed on the surface of HTi2NbO7-NS and the band gap energy of CeO2/HTi2NbO7-NS nanocomposite was reduced compared with its precursor. The type-II heterojunction was formed due to suitable band structures of host and guest materials. The CeO2/HTi2NbO7-NS nanocomposite owns the best adsorption capacity and photocatalytic oxidation activity, which was mainly attributed to the lower band gap and efficient separation of electron-hole pairs of CeO2/HTi2NbO7-NS nanocomposite.Graphical Unlabelled Image

Herein, we report the synthesis of CQDs by carbonizing an organic molecule, 1,7′-Dimethyl-2′-propyl-1H,3′H-[2,5′]bibenzoimidazolyl (DPBI). The crystallinity of DPBI-based CQDs is confirmed by XRD results, where, the observed peak at 25.8° is attributed to the reflection plane (002). Further, the results from HRTEM studies revealed that the morphology of the particles were spherical in shape with an average size between 2 and 3 nm and interplanar spacing 0.329 nm between two lattice fringes. The biological activity of as-prepared CQDs has been tested with respect to its inherent antitumor property, where the CQDs exhibited significant anti-cancer property against breast cancer cell lines in vitro and also showed specificity of action against tumor cells in ex ovo chick choreoallentoic membrane (CAM), which was used as in vivo model to study differential action of CQDs, wherein they show least cytotoxicity to normal cells, which is concordant with the in vitro study carried out to analyze activity of CQDs on red blood cells (RBCs) and white blood cells (WBCs).Graphical abstractUnlabelled Image

           isomers
    • Abstract: Publication date: Available online 30 December 2018Source: Inorganic Chemistry CommunicationsAuthor(s): Assia Midoune, Abdelatif Messaoudi, Yousef Boumedjane DFT calculations are presented for a series of tetrathiafulvalene (TTF) derivatives which, in association with tetracyano-p-quinodimethane (TCNQ) units, form π stacked, solid state compounds. The geometric and electronic features of eight differently substituted TTF units (some with two Se in place of S heteroatoms) are determined by DFT optimizations, each one bearing the 0, +1 and +2 charges. The minor deformations from planarity observed in the uncharged species disappear upon the electron removal. The delocalized π character of the HOMO with prevailing antibonding character between the C and S (Se) atoms justifies the geometric effects on the unit upon the release of the electrons and possibly the stacking of the units. Energy considerations indicate the parent TTF species is be less prone toward oxidation than its various derivatives. Finally, an important correlation emerges between the studied organic molecules and known square planar bis-dithiolene d8 metal complexes, also with propensity toward redox isomerism.Graphical abstractDFT calculations on up to nine differently substituted tetrathiafulvalene (TTF) units and their potential mono- and di-cationic derivatives highlight the subtle effects of a π delocalized frontier MO. This may favor one electron loss upon the TTF π stacking in the solid state in association with that of tetracyano-p-quinodimethane (TCNQ) which becomes monoanionic.Unlabelled Image

Thorough characterization of LDHs were done by using X-ray diffraction, Fourier-transform infrared spectroscopy, BET surface area, Transmission electron microscopy and CHNS elemental analysis methods. Among the microwave synthesized LDHs, ZnAl-NO3 has shown superior adsorption capacity for Congo red (CR) in aqueous solution than its counter ZnAl-CO3 LDH which was attributed to enhanced porosity and acidic property of the ZnAl-NO3 LDH. Adsorption capacity of the LDH adsorbents has been tested using various concentrations of CR ranging from 100 to 1200 ppm in water and the monolayer adsorption capacity of ZnAl-NO3 was observed as 571.43 mg g−1. It is important to note that adsorption studies were performed at ambient temperature and without maintaining pH of the solution. We have also studied the adsorption performance of the ZnAl-NO3-LDH for mixture of various anionic and cationic dyes in water using 25–100 ppm concentration of each dye in water. It has showed good adsorption affinity for anionic dyes over cationic dyes. In addition, the adsorption rates of CR onto ZnAl-NO3-MW are rather fast and CR adsorption equilibrium data obeys Langmuir adsorption isotherm model and kinetics data fitted to pseudo second-order kinetic model with correlation coefficients ranging from 0.998 to 0. 999.Graphical abstractUnlabelled Image

Both mercury(II) complexes, [Hg(L)(NO3)2] (1) and [Hg(L)(DMF)2](ClO4)2·DMF (2), with nitrate and perchlorate anions, respectively, show a typical endocyclic structure. Two nitrate ions in 1 occupy the coordination sites, while two DMF molecules participate to the coordination sphere in 2 remaining two perchlorate ions uncoordinated. It is found that the anion-exchange of 2 in the solid state induced the conversion to 1 which involves the rearrangement of the coordination sphere. In silver(I) complexations, nitrate afforded a cyclic dimer complex [Ag2(L)2(NO3)2] (3). While hexafluorophosphate gave a 1-D zigzag coordination polymer {[Ag(L)]PF6}n (4). Interestingly, triflate led to the isolation of a tetranuclear bis(macrocycle) complex, {[endoAg(L)(CF3SO3)]2[μ-exoAg2(CF3SO3)2]} (5), which are dominated by the coordination modes (endoAg and exoAg) of L toward two types of silver(I) centers. For instance, two endocyclic complex units, endoAg2(L)2(CF3SO3)2, are linked by exocyclic metallacycle, [μ-exoAg2(CF3SO3)2], to give a 4:2 (metal-to-ligand) stoichiometry. From the results, it is obviously clear that the role of anions mostly is responsible to such structural diversity based on the exo-coordination mode.Graphical abstractUnlabelled Image
       
  • Two pyrene-based S-containing atropisomers: Different structures and
           different Ag+-response behaviors of their monomer-excimer emission
    • Abstract: Publication date: Available online 28 December 2018Source: Inorganic Chemistry CommunicationsAuthor(s): Ying-ying Jin, Qi Fang, Shi-qian Zhang, Zhi-qiang Liu Different structures and different Ag+-response behaviors of a pair of pyrene-based S-containing atropisomers, namely s-BSPPy and a-BSPPy, have been investigated. The calculated high rotation barrier indicates that the two atropisomers are non-interconvertible. In polar solvents, s-BSPPy exhibits excimer emission but a-BSPPy does not. Based on the X-ray structures and the DFT calculated intermolecular interactions, the excimer of s-BSPPy is suggested to take a non-parallel edge-to-face λ-shaped geometry. Especially, s-BSPPy exhibits ratiometric excimer-off and monomer-on emission as a unique response to Ag+ in solutions, while no ratiometric Ag+-response was observed for a-BSPPy.Graphical abstractUnlabelled Image
       
  • Construction of Pt-decorated g-C3N4/Bi2WO6 Z-scheme composite with
           superior solar photocatalytic activity toward rhodamine B degradation
    • Abstract: Publication date: Available online 28 December 2018Source: Inorganic Chemistry CommunicationsAuthor(s): Yong Zhang, Chen Chai, Xiaochao Zhang, Jianxin Liu, Donghong Duan, Caimei Fan, Yunfang Wang Highly efficient visible-light-driven Pt-decorated g-C3N4/Bi2WO6 hybrid photocatalysts were successfully prepared via a photodeposition method. The microstructures and optical properties of the prepared samples were characterized by transient photocurrent experiments, X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), UV–vis diffused reflectance spectra (DRS), photoluminescence (PL), electron spin resonance (ESR) spectroscopy and X-ray photoelectron spectroscopy (XPS) techniques. FESEM and TEM images show that metallic Pt particles disperse on the surface of g-C3N4/Bi2WO6 hybrid. Pt-decorated g-C3N4/Bi2WO6 compsites exhibited excellent DRS attribute to the surface plasmonic resonance (SPR) of Pt particles and g-C3N4/Bi2WO6. The PL results verified that the suitable band potential of g-C3N4 and Bi2WO6 for construction of Z-type photocatalytic system. In the photocatalytic experiment, results showed that Pt(1%)-g-C3N4/Bi2WO6 photocatalysts displayed higher photocatalytic activity than either pure g-C3N4 or Bi2WO6 for the degradation of Rhodamine B (RhB). Additionally, the free-radical trapping experiments and ESR disclose that the hole (h+), superoxide radical (O2−) and hydroxyl radical (·OH) acted as reactive species. Based on above, a possible plasmonic Z-scheme mechanism for organics degradation over Pt-decorated g-C3N4/Bi2WO6 was proposed.Graphical abstractThe photocatalytic performance of g-C3N4/Bi2WO6 was greatly improved through construction of Pt-decorated Z-scheme composite, which the main reasons can be attributed to: first, the surface plasmonic resonance of metallic Pt could significantly enhance visible light absorption; second, metallic Pt was deposited on the surface of g-C3N4/Bi2WO6 microspheres and functioned as an electronconduction bridge, which played an important role in the electron transfer. Moreover, Z-scheme heterojunctions exhibit the dual advantages of having an improved charge–separation efficiency and enhanced redox ability.Unlabelled Image
       
  • Complexation and solvent extraction behaviour towards lanthanide ions with
           quercetin
    • Abstract: Publication date: Available online 28 December 2018Source: Inorganic Chemistry CommunicationsAuthor(s): Yuyu Fang, Yue Zhang, Qingrong Han, Mingyan Jia, Mei Zhang, Li Wang, Yuzhu Tan, Zhixing Cao, Yun Deng The complexation behaviour towards lanthanide (Ln) ions with quercetin (Q) was evaluated both in homogeneous phase and in liquid-liquid extraction process. As confirmed by UV–vis, fluorescence techniques and 1H NMR titration, Q can bind lanthanide ions through 4‑carbonyl and 3-hydroxyl of ring C with the stoichiometric ratio of 2:1 (Q:metal) in methanol solution. The binding constants for Q and Eu(III) (K1 = (3.87 ± 0.20) × 104 M−1, K2 = (2.56 ± 0.15) × 103 M−1) are slightly higher than that of Q-La(III) (K1 = (2.01 ± 0.15) × 104 M−1, K2 = (1.53 ± 0.12) × 103 M−1) and Q-Yb(III) (K1 = (1.73 ± 0.12) × 104 M−1, K2 = (1.25 ± 0.22) × 103 M−1). Solvent extraction revealed that the extractability of Ln(III) was relevant to the acidity and salinity of aqueous phase and extraction efficiency was Eu(III) > La(III) > Yb(III) at the same acidity.Graphical abstractThe complexation behaviour towards lanthanide (Ln) ions with quercetin (Q) was evaluated both in homogeneous phase and in liquid-liquid extraction process, which is the first example of using natural flavonoids to construct extractant for selective recognition and separation of metal ions (especially f-block elements).Unlabelled Image

           (H2TMA = 3‑thiophenemalonic acid) for impedimetric humidity sensing
           with high performance
    • Abstract: Publication date: Available online 21 December 2018Source: Inorganic Chemistry CommunicationsAuthor(s): Yan-Yan Yin, Le-Xi Zhang, Xuan Wang, Bai-Lu Zhang, Xiang-Qian Gong, Lu Liu, Rong-Huan Sun A novel lead-based two-dimensional (2D) coordination polymer of [Pb(TMA)]n (named as PbL, H2TMA = 3-thiophenemalonic acid) was synthesized via a facile precipitation method at room temperature. The PbL shows a 6, 3-connected network of honeycomb topology with thiophene rings on each side of the layer. It is worth noting that unusual PbS weak bonds (3.39 Å) further link the honeycomb layers to generate a three-dimensional (3D) supramolecular framework. Taking inspiration from the 2D lamellar structure and abundant active sites (such as Pb2+ ions, O and S atoms), which will facilitate the adsorption and interaction of water molecules on PbL surface, an impedimetric humidity sensor was fabricated based on this framework. The PbL sensor exhibited high response, good repeatability, small hysteresis, as well as short response and recovery times. Finally, the humidity sensing mechanism of this PbL sensor has been discussed through complex impedance analysis, confirming the contributions of distinct charge carriers at different relative humidity (RH). This work provides a practical candidate for humidity sensors and further develops a new promising application for coordination polymers in electrical sensory devices.Graphical abstractA novel 2D honeycomb-layered topological coordination polymer with formula of [Pb(TMA)]n (noted as PbL, H2TMA = 3‑thiophenemalonic acid) was synthesized and fabricated to be an impedimetric humidity sensor.
