5-[N-乙酸根(4-吡啶基)]四唑为桥联配体的铜(Ⅱ)、镉(Ⅱ)配聚物(英文)

New Cu(Ⅱ) and Cd(Ⅱ) Coordination Polymers Employing 5-[N-acetato(4-pyridyl)] Tetrazolate as a Bridging Ligand

以5-[N-乙酸根(4-吡啶基)]四唑为桥联配体,分别与Cu(ClO)2·6H2O和CdCl2的水溶液反应,获得配聚物[Cu(a4-ptz)2·2H2O]n(1)和[{Cd(a4-ptz)·(H2O)2Cl}·H2O]n(2),2个化合物通过元素分析、IR、TGA等表征,并测定了它的晶体结构。结果表明:化合物1是一个二维四方格子结构的配位聚合体,化合物2含有四元环(Cd2Cl2)的一维Z-型聚合链。化合物2在280℃以下热稳定性好,并且不溶于一般溶剂,因此可成为潜在的荧光材料。

Two coordination polymers [Cu（a4-ptz）2·2H2O]n（1） and [{Cd（a4-ptz）·（H2O）2Cl}·H2O]n（2） were synthesized and characterized by elemental analysis, IR spectroscopy, thermal analysis, and X-ray crystal structure analysis. Complex 1 exhibits a 2D square grid polymeric structure with dimensions of 1.220 0 nm × 1.220 0 nm. Complex 2 possesses a 1D Z-type polymeric chain, which contains four-membered ring （Cd2Cl2）. The thermal stability of complex 2 up to about 280 ℃ （TGA measurement） and their insolubility in common solvents make it a good candidate for potential fluorescent materials.
