摘要/Abstract

摘要： 本文结合电化学测量和量子化学计算对Mo-Fe-S三元包合物的氧化还原特性进行了研究。用铂电极测得的该包合物在0.1MKClO₄-DMF溶液中的循环伏安图显现出两对氧化-还原峰,由此得到的电化学参数与EHMO计算结果都表明,电位较正的一对峰相应于Fe(Ⅲ)/Fe(Ⅱ)的氧化还原,反应不可逆。电位较负的一对峰相应于Mo(Ⅴ)/Mo(Ⅳ)的氧化还原反应半可逆。

Abstract: The cxidalion-rcduclion characteristic of the ternary clathratc compound {Mo[S₂CN(C₂H₅)₂]₄}⁺{FcCl₄}^-{(C₆H₅CH₂S)₂ was studied by electrochemical measurment in combinaticn with quantum-chemical calculations. The cyclic voltam-mogram of this ternary clathrate compound in 0.1 M KClO₄-DMFwith a platinum electrode was seen to have 2 pairs of oxidation-reduction peaks. Both the electrochemical parameters derived from the voltammogram and the results of EHMOcalculalions indicate that the pair of oxidation-reduction peak at relatively positive potentials corresponds to the oxidation-reduction reaction of Fc(Ⅲ)/Fe(Ⅱ) which is irreversible in nature, while the pair of oxidalion-reducticn peak at more negative potentials corresponds to the oxidation-reduction reaction of Mo(Ⅴ)/Mo(Ⅳ), which is scmircvcrsible. the calculations from experimental measurements are fairly in agremcnt with the theoretical calculalions.
