Synthesis,characterization and properties of the mononuclear complex[Ni(IDB)_2](CH_3COO)·ClO_4·4H_2O

报道含三齿配体N ,N 二 (2 苯并咪唑甲基 )亚胺的单核镍配合物 [Ni(IDB) 2 ](CH3 COO)·ClO4·4H2 O的合成。并进行了元素分析、摩尔电导、紫外 可见光谱、红外光谱、自旋共振谱和循环伏安研究。推测配合物中镍离子 (Ⅱ )为六配位的八面体结构 。

The synthesis of a mononuclear nickel(Ⅱ)complex [Ni(IDB) 2](CH 3COO)·ClO 4·4H 2O (1)is reported(the tridentate ligand IDB is[ N,N di(2 benzimidazolyl methyl)amino]).The elemental analysis,molar conductivity,ultraviolet and visible(UV Vis),infrared(IR),electron spin resonance(ESR)and cyclic voltammetry(CV)of the complex have been studied.Its coordination geometry was close to octahedron or distorted octahedron.The nickel(Ⅱ)atom in the cation of the complex had distorted octahedronal coordination geometry and was coordinated by six nitrogen atoms:four nitrogen atoms of benzimidazole groups and two amine nitrogen atoms from the ligand IDB.The complex is a good structure model of urease.
