摘要
合成了六种过渡金属苦味酸盐与三(2 苯并咪唑亚甲基)胺配合物,并通过元素分析、红外光谱、紫外-可见光谱和摩尔电导进行了表征,其结果表明配合物的组成为[ML(Pic)]Pic(M=Mn2+、Co2+、Ni2+、Cu2+、Zn2+、Cd2+;L=三(2 苯并咪唑亚甲基)胺;Pic=苦味酸根阴离子),中心离子的配位数为5,两个苦味酸根离子只有一个和中心离子直接配位,所有的配合物在丙酮中均表现为1∶1型电解质。
Six kinds of transition metal picrate complexes having the stoichiometric formula 〔MLPic〕Pic(M=Mn2+?Co2+?Ni2+?Cu2+?Zn2+?Cd2+);L=tris(2benzimidazylmethyl)amine;Pic means picrate anion) have been synthesized and characterized by EA, IR,UV and molar conductance.The results indicate that the coordination number of the complexes is 5.Between two picrate anions,only one coordinates directly with metal cation,and the other does not take part incoordination.All the complexes are 1∶1 electrolytes in acetone solution.
