| 摘 要： | 以3, 5-二甲基-1-羧甲基-4-吡唑甲酸和4, 4'-联吡啶为配体, 合成了1个单核锌(II)配合物Zn(4,4'-bpy)(Hcmdpca)2(H2O)3]·2H2O (1)和1个锌(II)的一维配位聚合物Zn(4, 4'-bpy)(Hcmdpca)2(H2O)]·3H2O (2)(H2cmdpca=3, 5-二甲基-1-羧甲基-4-吡唑甲酸；4, 4'-bpy=4, 4'-联吡啶), 并用元素分析、红外光谱、X-射线单晶衍射结构分析、热重分析等对其进行了表征。配合物1和2都属于单斜晶系, 空间群为P21/c。配合物1的锌离子都位于一个畸变的八面体构型中。配合物1中的独立结构单元间通过分子间氢键作用构成一个三维的超分子结构。而在2中, 锌离子位于一个畸变的四方锥构型中, 每个4, 4'-联吡啶分子桥联2个相邻的 锌(II)离子, 形成一个一维链；这些一维链和水分子通过分子间氢键进一步形成一个三维的结构。此外还考察了1和2的热稳定性和固体荧光性质。

| Abstract: | One monomeric complex Zn(4,4'-bpy)(Hcmdpca)2(H2O)3]·2H2O (1) and one 1D coordination polymer Zn(4,4'-bpy)(Hcmdpca)2(H2O)]·3H2O (2) (H2cmdpca=1-carboxymethyl-3,5-dimethyl-1H-pyrazole-4-carboxylic acid, 4,4'-bpy=4,4'-bipyridine) have been synthesized and characterized by elemental analysis, IR spectra, single crystal X-ray diffraction, thermogravimetric analysis. Complexes 1 and 2 all crystallize in the monoclinic system, space group P21/c. In 1, Zn(II) ion is located in distorted octahedral coordination geometry, discrete mononucleate units and water molecules are assembled into a 3D network. In 2, each Zn(II) ion is located in distorted square-pyramid geometry. Each 4,4'-bpy ligand bridges two adjacent Zn(II) ions, forming a 1D chain. These chains and water molecules are connected by hydrogen bonds, forming a 3D supramolecular network. The thermal stability and luminescent properties of the complexes are also investigated. |
