摘要: 报道了八齿配体N,N,N′,N",N"-五(2-苯并咪唑甲基)-二乙三胺(简写为DTPB)及其含镍双核配合物〔Ni2(DTPB)(C2O4)〕·(ClO4)2·CH3CH2OH·2H2O( )的合成.对( )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.推测配合物中每个镍离子( )为六配位的八面体结构.

Abstract: The synthesis of a octadentate (N8) ligand 〔N,N,N′,N",N"-penta (2-benzimidazolyl-methyl)-1,4,7-diethy lenetriamine〕(DTPB) and a dinuclear nickel (Ⅱ) complex〔Ni2(DTPB)(C2O4)〕·(ClO4)2·CH3CH2OH·H2O (Ⅰ) are reported.The characterization of dinuclear nickel complex were carried out by the element analysis,molar conductity,ultraviolet and visible(UV-Vis),infrared(IR),electron spin resonance(ESR) and cyclic voltammetry(CV).Its corrdination geometry maybe close to octahedron or distorted octahedron.The complex has ...
