新型配位聚合物[Zn(tca)_2(4,4′-bpy)]的合成、晶体结构及荧光性质

Synthesis,crytal structure and properties of a new coordination polymer [Zn(tca)_2(4,4′-bpy)]

利用水热法合成了新型配合物[Zn(tca)2(4,4′-bpy)](tca=trans-cinnamic acid,4,4’-bpy=4,4’-bipyridine).通过元素分析、红外、荧光和单晶X-射线对配合物进行了结构和性质表征.结构测定显示配合物属六方晶系,P-3空间群.配体tca呈现2种配位模式,分别是顺-顺桥式双齿和螯合双齿,最终配合物形成新颖的三维结构.性质测定表明配合物具有蓝色荧光性质.

A new coordination polymer [Zn（tca）2（4,4′-bpy）] has been synthesized under hydrothermal conditions（4,4′-bpy=4,4′-bipyridine,tca=trans-cinnamic acid）.The characterization and structure determination of complexe was studied by elemental analysis,infrared spectrum,fluorescence and single crystal X ray.The structure analysis indicates that the complex shows a hexagonal system,P-3 space group.Tca ligands show two kinds of coordination mode,namely syn,syn-bidentate and bridge bidentate chelating.Eventually,the complexe form new three-dimensional structure.The study of property shows that the complexe possesses the characteristic of fluorescence.
