Synthesis and Characterization of an One-dimensional Ladder-Like Coordination Polymer [Cd（nic）（bdc）0.5（H2O）2]n·2nH2O

此文介绍一个一维梯状镉配位聚合物[Cd(nic)(bdc)0.5(H2O)2]n·2nH2O(1)(Hnic=烟酸,H2bdc=1,4-苯二甲酸),并通过X-射线单晶衍射、元素分析、红外光谱、热重分析对其结构进行表征。梯形梯框为[Cd(nic)(H2O)2]+链,梯级为bdc2-配体。梯状长链通过氢键相互作用连接形成三维超分子网状结构,在室温下,聚合物1显示蓝色荧光性能。

This paper reports an one-dimensional ladder-like cadmium coordination polymer,[Cd( nic)( bdc)0. 5( H2 O)2]n·2 n H2 O( 1)[Hnic = nicotinic acid, H2 bdc = 1,4-benzenedicarboxylic acid ], characterized by X-ray crystallography,elemental analysis,IR spectra and TG analysis. The ladder rails are [Cd( nic)( H2 O)2]+chains,and the ladder rungs are bdc2-ligands. Ladder-like chains are connected into a three dimensional supramolecular network through hydrogen bonding interactions O-H…O. Coordination polymer 1 displays blue luminescent property at room temperature.
