含酰胺的三齿羧酸Zn(Ⅱ)配合物的合成、结构与性能
A zinc(Ⅱ)complex with amide-containing tridentate carboxylic acid ligand:Synthesis,structure and properties
摘要
Abstract
In order to investigate the structure and properties of Zn(Ⅱ)complex with carboxylic acid ligand containing amides,a metal complex {[Zn6(μ3-OH)2(BTCTB)4]·3DMF}n was synthesized by hydrothermal method using 3,3',3"-[1,3,5-benzenetriyltris(carbonylimino)]tris-benzoate acid(H3BTCTB),Zn(NO3)2·6H2O and N,N-dimethylformamide(DMF)as raw materials.The structure and properties of the complex were investigated by single crystal X-ray diffraction and fluorescence spectroscopy.The results showed that:① The Zn(Ⅱ)ion adopted a five-coordinated coordination mode,resulting in a dis-torted tetrahedral configuration of the complex.The complex exhibited a 2D bilayer structure with(3,6)-connected of secon-dary structural unit[Zn3(COO)6]bridged by μ3-OH.And the adjacent 2D double layer were arranged into a 3D supramolec-ular packing structure by π…π interaction.② Fluorescence spectrum analysis showed that the complex had good luminescent property and could be used as a good fluorescent material.关键词
