摘　　要：本文以含咪唑/三唑基的两种有机羧酸H_(2)L^(1)和H_(2)L^(2)(H_(2)L^(1)=2-(4-(1H-1,2,4-三唑-1-基)苯基)-1H-苯并[d]咪唑-5-羧酸;H_(2)L^(2)=2-(4-(1H-咪唑-1-基)苯基)-1H-苯并[d]咪唑-5-羧酸)为配体,在溶剂热条件下合成3种新的金属配合物[Co(HL^(1))_(2)(H_(2)O)_(4)](1),[Ni(HL^(1))_(2)(H_(2)O)_(4)](2)和[Mn(HL^(2))_(2)(H_(2)O)_(4)](3)。通过IR和X-射线单晶衍射对配合物结构进行表征。结果表明:配合物1~3属于单核零维结构,金属中心离子均为六配位的八面体配位构型。配合物1~3都是通过氢键作用连接构筑成的二维超分子结构。对三种配合物的磁性进行研究,结果表明:配合物1具有顺磁性相互作用,配合物2和3具有反铁磁性相互作用。并对1和3进行了电化学性能测试。结果表明:两种配合物可作为潜在的电容器电极材料。In this paper,two organic carboxylic acids H_(2)L^(1) and H_(2)L^(2)(H_(2)L^(1)=2-(4-(1H-1,2,4-triazol-1-yl)phenyl)-1H-benzo[d]imidazole-5-carboxylic acid;H_(2)L^(2)=2-(4-(1H-imidazol-1-yl)phenyl)-1H-benzo[d]imidazole-5-carboxylic acid)as the ligand,new complexes[Co(HL^(1))_(2)(H_(2)O)_(4)](1),[Ni(HL^(1))_(2)(H_(2)O)_(4)](2)and[Mn(HL^(2))_(2)(H_(2)O)_(4)](3)were synthesized under solvothermal conditions.The structure of the complex 1~3 was characterized by IR and X-ray single crystal diffraction.The results show that the complexes 1~3 belong to the mononuclear zero-dimensional structure,and the metal center ions are all six-coordinated octahedral coordination configurations.Complexes 1~3 were connected to two-dimensional supramolecular structures by hydrogen bonding.The magnetic properties of the three complexes were studied,and the results show that complex 1 has paramagnetic interaction,complexes 2 and 3 have antiferromagnetic interaction.The electrochemical performance of 1 and 3 were tested,the results show that the two complexes can be used as potential capacitor electrode materials.
