Through using two kinds of flexible bis(triazol)and bis(pyrazol)ligands,three novel 2D grid-like coordination comple-xes,[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,C3 O4=malonic acid),have been synthesized under hydrothermal condi-tions. In complex 1,the Cu2+ion is fused by four btb ligands,and two Cl-further coordinate with Cu2+ion to satisfy its six-coordina-tion mode. Adjacent cross-type[Cu(btb)4 Cl2 ]subunits link each other by sharing the btb ligands and a 2D grid-like layer is gener-ated. In complex 2,two Cu+ ions are bridged by the Cl atoms and H2 bdpm ligands to form a 2D grid layer. The chloro-bridges be-come the essential synthons of 2D structure of 2.Complex 3 contains 1D[Cd(H2bdpm)2]n2+chains,which are further connected by malonic acid molecules to build a 2D layer with triangular grids. The photoluminescence and photocatalytic properties of the comple-xes have also been studied in this paper.%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）2Cl2]（1），[Cu3（H2bdpm）Cl3]（2）and[Cd（H2bdpm）2（C3O4）]（3）。化合物1中Cu2＋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）4Cl2]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H2 bdpm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（H2 bdpm）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。
