摘要
用水热合成法得到了镉的2个配合物[CdCl(pybma)·H2O]n(1)和[Cd2(pybma)2(OH-BDC)]n(2)(Hpybma=2-(2-吡啶基)苯并咪唑基乙酸,OH-H2BDC=5-羟基-1,3-苯二酸),对它们进行了元素分析、红外光谱、XRD,热重,荧光等表征,并用X-射线单晶衍射测定了配合物的单晶结构。配位聚合物1属单斜晶系,P21/c空间群,配位聚合物2属三斜晶系,P1空间群。2个配合物都是二维层状结构,其中配合物1通过氢键作用形成三维网状结构。实验结果表明2个配合物都具有较好的荧光性质,可以作为潜在的荧光光学材料。
The compounds[CdCl(pybma)·H2O]n(1) and [Cd2(pybma)2(OH-BDC)]n(2)(Hpybma=2-(2-pyridinyl- benzimidazolyl) acetic acid, OH-H2BDC =5-hydroxy-1,3-benzenedicarboxylic acid) have been synthesized by hydrothermal methods and characterized by elemental analysis, IR spectra, XRD, TGA, fluorescence,and the crystal structures were determined by single-crystal X-ray diffraction. The compound 1 crystallizes in the monoclinic system, space group P21/c. The compound 2 crystallizes in the trielinic system, space group P1. Both compounds are two-dimensional (2D) layer structures, furthermore the compound 1 is extended into three- dimensional network by hydrogen bonds. The experimental results show that two compounds have good fluorescence properties and can be used as potential optical materials. CCDC: 751164, 1; 751165, 2.
