Using two 8-hydroxyquinolinate ligands (L1-MOM and L2-MOM) containing 3-pyridyl or 4-pyridyl groups, five novel coordination polymers, namely, [Zn3(L1)6] (1), [Zn(L1)2]·2MeOH (2), [Zn(L2)2] (3), [Cd(L2)2] (4), and [Cd4(L1)6]·13H2O (5), were synthesized and characterized by a variety of techniques. Single-crystal X-ray structures have revealed that these coordination polymers exhibit a structura...

Two new Mg(II)-based and Zn(II)-based coordination polymers, {[Mg3(BTB)(DMA)4](DMA)2}n (1, H3BTB=1,3,5-benzenetrisbenzoic acid, DMA=N,N-dimethylacetamide) and {(H2NMe2)2[Zn3(BTB)2(OH)(Im)](DMF)9(MeOH)7}n (2, Im=imidazole, DMF=N,N-dimethylformamide), have been successfully synthesized and structurally characterized under solvothermal conditions. 1 contains a linear [Mg3(COO)6] cluster that conne...

The thermal transformation of zinc hydroxide sulphate hydrate to zinc oxide has been examined using synchrotron X-ray diffraction, thermogravimetric analysis, scanning electron microscopy, and surface area measurements. By collecting X-ray diffraction data in situ, we found that the dehydration of zinc hydroxide sulphate pentahydrate proceeded in discrete steps to form anhydrous zinc hydroxide ...

The synthesis of Mg3(NDC)3(DEF)4 (NDC = 2,6-naphthalenedicarboxylate, DEF = N,N-diethylformamide, 1), the first porous metal-organic framework solid incorporating Mg2+ ions, is reported. Its structure consists of linear Mg3 units linked via NDC bridges to form a three-dimensional framework, featuring one-dimensional channels filled with DEF molecules. Significantly, its framework is fully analo...

The surface-modified zinc phosphate (Zn3(PO4)2) nanocrystals were synthesized by a facile and efficient one-step ultrasonic-template-microwave (UTM) assisted route. The crystal structure, optical properties and morphologies of zinc phosphate nanocrystals were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, Raman spectroscopy and transmission electron microscope. And...

The title complex, systematic name hexa-kis-(μ2-4-tert-but-oxy-4-oxobut-2-en-2-olato)-1:2κ(9) O (2),O (4):O (2);2:3κ(9) O (2),O (4):O (2)-trizinc, [Zn3(C8H13O3)6], syn-the-sized from tert-butyl aceto-acetate and di-ethyl-zinc, consists of trinuclear centrosymmetric mol-ecules of an approximate C 3i symmetry. The three metal cations are arranged in a linear fashion, with the central Zn(II) atom ...

Transparent, needle-like single crystals of the isostructural compounds [Sb4O7+3δX4][Zn3]1+δ (X = Cl, Br, I) δ ≈ 0.2 were obtained from chemical reactions in evacuated and sealed silica tubes. First, the average structure was solved in P21/n but the model refined poorly and a lowering of the symmetry to the 3 + 1 dimensional space group P21(α0γ)0 gave a significantly better fit to the data. Thi...

Zinc-solubilizing bacteria (ZSB) are potential and ideal substitutes for Zn supplement. Currently, limited reports available on the displaying capability to transform insoluble forms of zinc (Zn) an form. Therefore, attempts were made identify characterize Zn-solubilizing strains from chickpea rhizosphere growth promotion biofortification. Sixty-one isolated different parts Indo-Gangetic plains...
