摘要
利用循环伏安法测定了四核钼簇合物Ｍｏ_４Ｓ_４（μ－ＯＡｃ）_２（ｄｔｐ）_４在ＣＨ_３ＣＮ，ＤＭＦ，ＤＭＳＯ等溶剂中的氧化还原半波电位（Ｅ_（１／２）），对其氧化还原峰进行了归属，结果表明在ＣＨ_３ＣＮ中存在一个单电子的氧化过程和二个单电子的还原过程，而在ＤＭＦ和ＤＭＳＯ中只存在二个单电子的还原过程。同时还探讨了溶剂的ＤＮ数对该簇合物电化学性质的影响。
Electrochemical behavior of tetranuclear molybdenum cluster compound [Mo_4S_4(μ-OAc )_2 (dtp)_4] in three nonaqueous solvents were studied by cyclic voltammetry in this paper.The potentials of the redox reactions were measured.Three(or two) pairs of the redox peaks are assigned.And the solvent effect on the electrochemical characteristics of this cluster compound is also discussed preliminarily.
