摘要
利用水热法,以2-(4-羧基-苯基)咪唑-4,5-二羧酸(H3L)为主配体,在辅配体1,10-菲咯啉(1,10-phen)和1,4-二(1-咪唑基)苯(dib)的调控作用下得到2个新的镉(Ⅱ)配合物:[Cd2(HL)2(1,10-phen)2(H2O)2](1),{[Cd(HL)(dib)0.5(H2O)2]·2H2O}n (2)。并通过单晶X射线衍射、元素分析、热重分析、粉末X射线衍射、红外光谱、Hirshfeld表面分析和密度泛函理论量化计算对1和2进行了分析和表征。配合物1和2均属于三斜晶系和■空间群,且1为零维结构,2为一维链状结构。
Two new cadmium(Ⅱ) complexes were synthesized by hydrothermal method with 2-(4-carboxy-phenyl)-imidazole-4,5-dicarboxylic acid(H3L)through the auxiliary ligands 1,10-phenanthroline(1,10-phen)and 1,4-bis(1-imidazolyl)benzene(dib)coordination regulation effect,[Cd_(2)(HL)_(2)(1,10-phen)_(2)(H_(2)O)_(2)](1)and{[Cd(HL)(dib)0.5(H_(2)O)_(2)]·2H_(2)O}n(2).1 and 2 were analyzed and characterized by single crystal X-ray diffraction,element analysis,thermo-gravimetric analysis,powder X-ray diffraction,infrared spectroscopy,Hirshfeld surface analysis,and density func-tional theory quantification calculations.Single crystal X-ray diffraction shows that 1 and 2 belong to the triclinic system and the P1 space group,and 1 forms a zero-dimensional structure,2 forms a one-dimensional chain struc-ture.CCDC:2044127,1;2044128,2.
