摘　　要：合成了四种三核钼钨簇合物（［Ｍｏ３Ｌ］２＋，［Ｍｏ２ＷＬ］２＋，［ＭｏＷ２Ｌ］２＋，［Ｗ３Ｌ］２＋，其中Ｌ＝［（μ３－Ｏ）２（μ－ＣＨ３ＣＯＯ）６（Ｈ２Ｏ）３］）。并研究了四种簇合物在铂电极上的电化学特性，结果表明：在０．０１ｍｏｌ／Ｌ簇合物的水溶液中，［Ｍｏ３Ｌ］２＋，［Ｍｏ２ＷＬ］２＋出现两个氧化峰，两个还原峰。［Ｗ３Ｌ］２＋，［Ｗ２ＭｏＬ］２＋则出现三个氧化峰和两个还原峰，四种簇合物的电化学性质不同，主要是由于钼钨的外层电子排布不同造成的。Four trinuclear molybdenum and tungsten cluster compounds ( 2+ , 2+ , 2+ , 2+ , L=[ μ 3 O) 2( μ CH 3COO) 6(H 2O) 3]) were prepared in this paper. Electrochemical behavior of them on platinum were investigated. In 0.01 mol/L water solution, two oxidation peaks and two reduction peaks were found in present of 2+ or 2+ . Three oxidation peaks and two reduction peaks were found in present of 2+ or 2+ . The results of experiment indicated that the four cluster compounds have different electrochemistry property because there are different out shell electron configurations for molybdenum and tungsten.
