在水热条件下合成了3个配合物,[Cd0.5(o-bix)NO3]n(1),[Cd(m-bix)2(H2O)2·2NO3]n(2)和[Cd(2,3-pidc)(p-bix)]n(3)(bix=二(1-亚甲基咪唑)取代苯,2,3-pidc=2,3-二羧基吡嗪).配合物1具有一维链状结构,配合物2具有双重相互平行穿插的结构,配合物3则是二维平面结构.同时,对配合物1-3进行了热稳定性和荧光性质的研究.配合物1的结构在215℃以下是稳定的.配合物2从82到150℃失去参与配位的水分子.配合物3在273℃以下结构保持稳定.在室温下,360 nm处的荧光激发导致配合物1、2、3分别在450、460、460 nm处有荧光发射.%Three complexes, [Cd0.5(o-bix)NO3]n(1), [Cd(m-bix)2(H2O)2·2NO3]n (2) and [Cd(2,3-pidc)(p-bix)]n (3) (bix=bis(imidazol-1-ylmethyl)-benzene, 2,3-pidc=2,3-pyrazinedicarboxylic acid), have been synthesized under hydrother-mal conditions. Complex 1 shows a one-dimensional (1 D) chain structure, complex 2 features a 2-fold parallel inter-penetrated framework, and complex 3 represents a two-dimensional (2D) layer structure. The thermal stabilities and fluorescent properties of complexes 1～3 are investigated.
