利用不同的方法由配体4-(4-咪唑基-亚甲基氨基)苯甲酸(H2L)和过渡金属盐反应合成了3个配合物[M(HL)2(H2O)2](M(Ⅱ)=Mn(Ⅱ)(1),Cd(Ⅱ)(2),Cu(Ⅱ)(3)),进行了X-射线单晶衍射等表征。晶体结构解析结果表明:配合物1～3都属于三斜晶系,P1空间群,分子之间通过丰富的氢键相互作用最终形成了三维超分子结构。并且研究了配合物的热稳定性和电化学性质。 Three complexes [M (HL) 2 (H2O) 2] (M (OH) 2) were synthesized by the reaction of 4- (4-imidazolylmethyleneamino) benzoic acid (H2L) and transition metal salts using different methods (Ⅱ) = Mn (Ⅱ) (1), Cd (Ⅱ) (2) and Cu (Ⅱ) (3) were synthesized and characterized by X - ray single crystal diffraction. The crystal structure analysis results show that complexes 1 to 3 all belong to the triclinic system, P1 space group, and the molecules finally form a three-dimensional supramolecular structure through abundant hydrogen-bonding interactions. The thermal stability and electrochemical properties of the complexes were also studied.
