摘要
本文利用柔性双吡唑和三氮唑为配体,水热条件下合成了三个新的二维格子状的配位化合物,[Cu(btb)_2Cl_2](1),[Cu_3(H_2bdpm)Cl_3](2)and[Cd(H_2bdpm)2(C_3O_4)](3)。化合物1中Cu^(2+)为六配位结构,分别与四个N原子和两个Cl原子配位。相邻的[Cu(btb)_4Cl_2]单元共用btb配体从而形成了二维网状结构。化合物2中Cu+通过Cl原子和H_2bdpm配体链接,形成二维结构,氯桥在二维结构的形成中起到重要的作用。在化合物3的结构中包含一维链状的[Cd(H2bdpm)_2]_n^(2+),多个链状结构通过丙二酸分子连接形成了含有三角格的二维结构。此外,我们也对化合物的荧光性质和光催化性质进行了研究。
Through using two kinds of flexible bis( triazol) and bis( pyrazol) ligands,three novel 2D grid-like coordination complexes,[Cu( btb)2Cl2](1),[Cu3(H2bdpm) Cl3](2)and[Cd(H2bdpm)2(C3O4)](3)(btb = 1,4-bis(1,2,4-triazol-1-y1)butane,H2 bdpm = 1,1'-bis( 3,5-dimethyl-1H-pyrazolate) methane,C3O4= malonic acid),have been synthesized under hydrothermal conditions.In complex 1,the Cu-(2+) ion is fused by four btb ligands,and two Cl-further coordinate with Cu^2+ ion to satisfy its six-coordination mode.Adjacent cross-type[Cu( btb)4Cl2]subunits link each other by sharing the btb ligands and a 2D grid-like layer is generated.In complex 2,two Cu+ions are bridged by the Cl atoms and H2bdpm ligands to form a 2D grid layer.The chloro-bridges become the essential synthons of 2D structure of 2. Complex 3 contains 1D[Cd( H2bdpm)2]n^2+ chains,which are further connected by malonic acid molecules to build a 2D layer with triangular grids.The photoluminescence and photocatalytic properties of the complexes have also been studied in this paper.
