new coordination polymer {[Zn(CF3COO)2(C5H5ON)]·H2O}n was synthesized based on the reaction of zinc(Ⅱ) trifluoroacetate and 3-hydroxypyridine(C5H5ON) in methanol medium for the first time. The structure of the coordination polymer was confirmed by IR, 1H NMR, elemental analysis and thermal analysis. The crystal structure of the coordination polymer was also determined by X-ray single crystal diffraction. The crystal belongs to monoclinic system with space group P21/m, and crystallographic data of the coordination polymer are: a= 0.863 1(4) nm, b=0.717 7(3) nm, c=1.116 4(5) nm, α=γ=90°, β=107.542(6)°, V=0.659 4(5) nm3; Dc=2.037 g·cm-3; Z=2; F(000)=400; μ=1.969 mm-1. Zinc(Ⅱ) atom lies at the center of an octahedron formed by the coordination of zinc atom and six O atoms which come from four different trifluoroacetate ions and two different 3-hydroxypyridine molecules where each trifluoroacetate ion and 3-hydroxypyridine are coordinated to two different zinc ions to form coordination polymer.

The novel copper(Ⅱ) coordination polymer with 2-oxo-propionic acid benzoyl hydrazone and hexamethylenetetramine ligands, {Cu(μ2-C10H8N2O3)( μ2-C6H12N4)1/2}n (C10H8N2O32- is the dinegative ion of 2-oxo-propionicacid benzoyl hydrazone), has been synthesized and characterized by elemental analysis and IR spectroscopy. The crystal structure was determined by single crystal X-ray diffraction analysis. The results show that the crystal of the title coordination polymer belongs to monoclinic space group C2/c, the cell parameters are as follows: a=1.787 5(2) nm, b=0.730 93(9) nm, c=2.038 2(2) nm, β=92.890(2)°, and V=2.659 6(5) nm3, Z=8, Dc=1.687 Mg·m-3, μ(Mo )=1.659 mm-1, F(000)=1 384, R=0.031 1, wR=0.079 0 for 2 454 observed reflections (I>2σ(I)) out of 2887 unique reflections. In this copper(Ⅱ) coordination polymer, each copper(Ⅱ) ion is five-coordinated with a geometry of distorted square-pyramid. Two oxygen atoms of the carboxyl of each C10H8N2O32- acts as a bridge to bond two neighboring copper(Ⅱ) ions, leading to an infinite one-dimensional chainlike coordination polymer. Each chain is linked by coordinated hexamethylenetetramines with its neighbors to form an infinite two-dimensional network structure. CCDC: 255347.  相似文献

The crystal of binuclear zinc complex Zn2(dhaash)2(py)4 was obtained in DMF and pyridine, where H2dhaash is 2,4-dihydroxy-5-acetylacetophenone-N-salicylhydrazone. It has been characterized by IR, UV, element analysis and X-ray single crystal diffraction. The crystallographic data were as follows: monoclinic system, space group P21/c, a=1.108 98(11) nm, b=1.640 84(16) nm, c=1.445 14(14) nm, β=108.617(2)°, Z=2, V=2.492 1(4) nm3, Dc=1.466 g·cm-3, Mr=1 099.74, μ=1.031 mm-1, F(000)=1 136 and the final R=0.044 8 and wR=0.105 8 for 4 143 observed reflections with I≥2σ(I), respectively. The X-ray crystal structure analysis revealed that, in the centrosymmetric binuclear complex molecule, two zinc(Ⅱ) centers are linked by two oxygen atoms (O(3) and O(3A)), respectively. Zn(1)…Zn(1A) distance is 0.314 81(6) nm, O(3)…O(3A) distance is 0.270 4(2) nm. Every zinc(Ⅱ) ion has an elongated octahedral coordination. For example, the two pyridine nitrogen atoms, one oxygen atom and one nitrogen atom from salicylhydrazone, one oxygen atom from 2,4-dihydroxy-5-acetylacetophenone in one dhaash2- ligand and one oxygen atom from 2,4-dihydroxy-5-acetylacetophenone in another dhaash2- ligand coordinated to zinc(Ⅱ) ion, respectively. Two zinc(Ⅱ) ions and all the 72 non-hydrogen atoms in the two dhaash2- ligands are in the same plane. CCDC: 261929.  相似文献

The title compound [Zn(DMF)6]H2SiW12O40·(CH3)2NH was synthesized in mixed solvent of aqueous and acetonitrile, and its crystal structure had been determined using single crystal X-ray diffraction. The crystal belongs to monoclinic, space group C2/m, a=2.0654(4)nm, b=1.3306(3)nm, c=1.3194(3)nm, β=119.59(3)°, V=3.1531(11)nm3, Dc=3.606Mg·m-3, Z=2, R=0.0462, Rw=0.0836. The title compound comprises of a [Zn(DMF)6]2+ unit, a polyanion and a free (CH3)2NH molecule. The ESR spectrum of the title compound shows that charge-transfer between organic groups and polyanion takes place under irradiation of the sunlight in solid state. The TG study of the title compound shows that it had four stages of the weight loss, and the increase of the de-composition temperature for the polyanion shows that the stability of the polyanion was enhanced due to the influence of Zn2+ ion.
