A 2D copper coordination polymer of [Cu2(3-PyOH)2(EDTA)]n (EDTA4-=ethylenediaminetetraacetate quadrivalent anion C10H12N2O8, 3-PyOH=3-hydroxypyridine) was synthesized and characterized by the element analysis, IR and single crystal X-ray diffraction. The title complex crystallizes in monoclinic system with space group P21/c, a=1.327 5(3) nm, b=0.930 39(19) nm, c=0.948 44(19) nm, β=108.21(3)°, and V=1.112 8(4) nm3, Z=2, R=0.025 2, wR=0.066 1. Each copper(Ⅱ) atom is five-coordinated by three O atoms and one N atom from two different EDTA4- groups and one N atom from 3-PyOH ligand, forming a distorted square-pyramidal coordination geometry. Two adjacent copper(Ⅱ) atoms are bridged by the bis-tetradentate EDTA4- groups, constructing a two-dimensional layer structure along bc plane. The adjacent Cu…Cu distances are 0.502 5(3) and 0.611 3(3) nm. CCDC: 618806. 相似文献

A one-dimensional (1D) Z conformation coordination polymer, [Ag(bix)(NO3)(H2O)]n was obtained by the reaction between AgNO3 and flexible ligand of 1,4-bis(imidazol-1-ylmethyl)-benzene under hydrothermal conditions. It crystallizes in triclinic with space group P1. The crystallographic data of the compound are: a=0.777 1(2) nm, b=1.043 4(3) nm, c=1.082 7(3) nm, α=71.403(4)°, β=80.946(5)°, γ=88.794(4)°. The 1D chainlike structure was connected by π-π interaction between phenyl rings, leading to a 2D layered network. The lattice water and the NO3- anions were involved between the layers, therefore the 2D layered structure further extended to an intricate 3D framework. CCDC: 257100. 相似文献

聚合物[Zn(pht)(pzH)2]n的合成,晶体结构与荧光性质 总被引:2,自引:2,他引:2
A Zn(Ⅱ) coordination polymer [Zn(pht)(pzH)2]n (where pht2-=dianion of o-phthalic acid, pzH=pyrazole) has been synthesized and the structure was determined by X-ray diffraction. The complex crystallizes in the monoclinic space group P21/c, a=0.821 39(10) nm, b=1.662 2(2) nm, c=1.156 42(14) nm, β=100.349(2)°, V=1.5532(3) nm3, Z=4. Both carboxylate groups of the phthalate dianion coordinated in a monodentate mode bridged two Zn(Ⅱ) atoms forming the structure of 1-D chain. The pyrazole ligands play two different roles: one only coordinates the metal atom and the other joins the coordination polymer into a 2-D sheet via N-H…O and C-H…O hydrogen bonds besides the coordination property. A blue photoluminescence peak at 435 nm was observed in solid state at room temperature. CCDC: 227946. 相似文献

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 Copper(Ⅰ) supramolecular complexes of 4,5-bis(methylthio)-1,3-dithiole-2-thione (C5H6S5), [Cu(C5H6S5)(SCN)]∞ 1 and [Cu(C5H6S5)I]∞ 2, have been prepared and characterized. X-ray structure analysis for complex 1 reveals that the infinite chain structure with polymeric stairs of different lengths is formed through the coordination mode (μ3) of the thiocyanate bridges. The shorter interchain S…S contacts give rise to a three-dimensional network structure. CCDC: 215668. 相似文献

A coordination complex of [Cu(bpb)0.5(CH3COO)2]n (bpb=1,4-bis(pyridine-3-aminomethyl)benzene) has been synthesized and characterized by elemental analysis, IR spectra, TG and X-ray single crystal diffraction. The title complex crystallizes in triclinic with space group P1, a=0.771 98(15) nm, b=0.827 62(17) nm, c=1.116 0(2) nm, α=96.71(3)°, β=90.03(3)°, γ=105.39(3)°, and V=0.682 4(3) nm3, Z=2, R=0.042 4, wR=0.091 1. The title complex is composed of dicopper tetracarboxylate units. Copper(Ⅱ) atom asumes a square-pyramidal coordination geometry formed with one pyridyl N atom from bpb and four O atoms from four bridging acetate anions. Two adjacent dicopper tetracarboxylate units are linked into a 1D chain by the bpb ligands, which were further connected by inter-chain hydrogen bonds to form a 2D network structure.

2,4,6-Tris(2-pyridyl)-1,3,5-triazine (tptz) undergoes hydrolysis in the presence of copper(II) acetate affording bis(2-pyridylcarbonyl)amido-copper(II) and free 2-pyridylcarboxylic anion. Two compounds of formulas [Cu(NC5H4COO)2]·2H2O (1) and [Cu(NC5H4CO)2N(tptz)](N(CN)2)·7H2O (2), where NC5H4COO? and (NC5H4CO)2N? are 2-pyridylcarboxylate and bis(2-pyridylcarbonyl)amido-anion, respectively, were obtained from methanol/ethanol solution of tptz with copper acetate; they were characterized by element analysis and single crystal X-ray diffraction method. Single crystal XRD analysis shows that in complex 1 coordination number around Cu atom is 4 with distorted square-planar coordination geometry and in complex 2 coordination number around Cu atom is 6 with distorted octahedral geometry.
