摘要
报导了一种含 1,2 ,二 -四 - [苯并咪唑基 -甲基氨基 ]-反式环己烷铁 (Ⅱ )型配合物的合成 ,用元素分析、摩尔电导和紫外表征 ,用单晶X -射线衍射法测得配合物的晶体结构 ,晶体属于单斜晶系 ,空间群为C2 /c ,其晶胞参数为a =1.5 12 2 (3)nm ,b =1.2 792 (3)nm ,c =1.974 6 (4)nm ,β =10 1.0 3(3)° ,z=4 ,偏离因子R =0 .0 5 6。每个结构单元中Fe(Ⅱ )与配体CTB的四个苯并咪唑氮原子和两个烷胺氮原子以畸变八面体方式配位 ,烷胺氮与两个苯并咪唑氮原子构成了四方形平面 ,另外两个苯并咪唑氮原子占据轴向位置 ,并用循环伏安法对配合物进行了电化学性质的测试。
This paper reports the synthesis,and characterization of the complex of N,N,N',N'-tetrakis (benzimidazol-2-yl-methyl)-1,2-diaminocyclo-hexane with iron(Ⅱ).The structure of Cl 2·2H 2O is determined by single Crystal X-ray diffraction .The complex crystallizes is the monoclinic Space,C2/c group with a=1.5122(3)nm, b=1.2792(3)nm, c=1.9746(4)nm,β=101.03(3)°,Z=4,R 1=0.056.In the complex, Fe(Ⅱ) is coordinated by four nitrogen atoms of benzimidazole and two aliphatic amine nitrogen atoms from the ligand CTB, forming a highly distorted octahedral, The activity studies of electric chemisty is determined by Cyclic Voltammetry.
