双钼配合物氧化还原特性的研究

A Study on the Oxidation-Reduction Characteristic of the Bimolybdenum Complex Compound

以MoCl_(5)和二乙胺基硫代甲酸钠为原料,在AlCl_(3)存在下于甲醇溶液中反应,生成双钼配合物Mo[S_(2)CN(C_(2)H_(5))_(4)]^(+)[MoCl_(6)]用循环伏安法研究了氧化还原特性。 (一)实验部分 由JH-2C型恒电位仪,XFD-8型讯号发生器和LZ_(3)-20型函数记录仪组成循环伏安的测量装置,电解池为三电极结构,研究电极和辅助电极均为光滑的铂金片,参比电极为222型饱和甘汞电极,通过盐桥和鲁金毛细管相联,测定循环伏安曲线前溶液先通入净化了的氮气以除去溶液中可能存在的氧,测定时停止通氮。

The cyclic voltammogram of bimolybdenum complex compound is reported. It is shown that there are a pair of redox peaks and one reduction peak in the cyclic voltammogram. The results indicate that the redox peak pair is corresponding to the redox reaction of Mo[S_(2)CN(C_(2)H_(5))_(2)]_(4)^(+), which is semireversible, but another reduction peak is corresponding to the reduction reaction of MoCl_(6)^(-), which is irreversible.
