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。
In this paper, three new two-dimensional lattice coordination compounds were synthesized by hydrothermal method under the conditions of flexible bipyrazole and triazole ligands [Cu (btb) 2Cl 2] (1), [Cu 3 (H 2bdpm) Cl 3 ] (2) and [Cd (H 2bdpm) 2 (C 3 O 4)] (3). Cu 2+ in compound 1 is hexacoordinated and coordinated with four N atoms and two Cl atoms respectively. Adjacent [Cu (btb) _4Cl_2] units share the btb ligand to form a two-dimensional network structure. Cu 2+ in compound 2 is linked to H 2bdpm ligand via Cl atom and forms a two-dimensional structure. Chloride bridge plays an important role in the formation of two-dimensional structure. One-dimensional chain-like [Cd (H2bdpm) _2] _n ~ (2+) was contained in the structure of compound 3, and several chain structures were connected by malonic acid molecules to form a two-dimensional structure with triangular lattices. In addition, we also studied the fluorescence and photocatalytic properties of the compounds.
