摘要
为了探究含酰胺的羧酸配体Zn(Ⅱ)配合物的结构与性能,以3,3′,3″-[1,3,5-苯三基三(羰基亚氨基)]三苯甲酸(H3BTCTB)、六水合硝酸锌以及N,N-二甲基甲酰胺(DMF)为原料,采用水热合成法制备了金属配合物{[Zn6(μ_(3)-OH)_(2)(BTCTB)_(4)]·3DMF}_(n),并利用X-射线单晶衍射和荧光光谱法探究其结构与性能.结果表明:①Zn(Ⅱ)离子以五配位的配位模式使配合物呈现扭曲的四面体构型,形成具有μ_(3)-OH桥连的[Zn_(3)(COO)_(6)]次级结构单元的(3,6)-连接的二维双层结构,之后通过π…π相互作用进一步形成了三维超分子结构;②荧光光谱分析结果显示配合物具有较好的荧光性能,可作为良好的荧光材料.
In order to investigate the structure and properties of Zn(Ⅱ)complex with carboxylic acid ligand containing amides,a metal complex{[Zn_(6)(μ_(3)-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(NO_(3))_(2)·6H_(2)O 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:①The 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[Zn_(3)(COO)_(6)]bridged byμ_(3)-OH.And the adjacent 2D double layer were arranged into a 3D supramolec-ular packing structure byπ…πinteraction.②Fluorescence spectrum analysis showed that the complex had good luminescent property and could be used as a good fluorescent material.
