钴配合物[Co(phen)(pydc)(H_2O)]·2H_2O的合成、表征及荧光性质

Synthesis,Characterization and Photoluminescence Property of Cobalt Complex [Co(phen)(pydc)(H_2O)]·2H_2O

采用溶剂挥发法合成了钴配合物[Co(phen)(pydc)(H2O)].2H2O,通过元素分析、红外光谱、紫外光谱、热重和X-射线单晶衍射对其结构进行了表征。该化合物属于三斜晶系,Pī空间群。六配位的Co()为畸变的八面体构型。单胞分子间通过氢键及π-π堆积作用相互形成三维网状结构。荧光测试表明配合物在369nm(λmax)具有强的荧光发射。

A cobalt complex [Co（phen）（pydc）（H2O）]·2H2O was synthesized by solution evaporation method,and its structure was characterized by elemental analysis,IR spectra,UV spectra,TG and X-ray single crystal diffraction analysis.The complex is triclinic crystal system and space group Pī.The 6-coordinated geometry of the Co（Ⅱ） is a distorted octahedron configuration.A three-dimensional network structure is constructed by hydrogen bonds and π-π stacking interactions between single cells.Fluorescence spectral analysis shows that the complex has a strong fluorescence-emission at 369nm（λmax）.
