摘要 采用溶剂热合成方法得到了3个配合物[Zn(TBA)_2](1)、[Cd(TBA)_2](2)和[Ni(TBA)_2](3)[HTBA=4-(1,2,4-三唑-1-基)苯甲酸],用X-射线衍射测定了配合物的晶体结构,结果表明,三个配合物同构,均为单核结构,中心金属离子与2个配体三氮唑中的氮以及水分子的氧配位,形成了1个以金属离子为中心的扭曲八面体,配体羧基脱氢,但是羧基氧不参与配位,而是与配位水分子之间形成氢键,三维结构依靠氢键作用形成. Three complexes [Zn（TBA）2]（1）, [Cd （TBA）2] （2）and of [Ni（HTBA）2] （3） [HTBA=4-（1H-1, 2, 4-triazol-1-yl） benzoic acid] have been synthesized through solvothermal synthesis reactions and characterized by elemental analyses and single-crystal X-ray diffrac- tion analyses. The structures reveal that three complexes are isomorphous mononuclear molecules. The metal ion is coordinated in a distorted octahedral geometry defined by coordinated nitrogen and oxygen atoms. The carboxyl group of the ligand was dehydrogenized, but the oxygen atoms of the carboxyl group didn＇t participate in the coordination. Hydrogen bonds were formed between the oxygen atoms of the carboxyl group and coordinated water molecules, further piled up into a three-dimensional architecture by intermolecular hydrogen bonds.
