四钼簇合物的氧化还原特性

The Redox Characteristic of the Four-Molybdenum Clusters

通过电化学测量对本实验室合成的两种四钼原子簇化合物的氧化还原特性进行了研究。由循环伏安图的分析得出这些簇合物中的钼原子有不同的氧化还原特征。与MoCl_5和配合物[Mo(Etdtc)_4][MoCl_5]的循环伏安图比较,证实正电位区的两个峰是四钼原子簇化合物中金属-金属键的氧化特性。

The redox characteristic of two kinds of four-molybdenum clusters made by our lab. was studied by electrochemical measurement. It was indicated by analysis from the cyclic voltammograms that the molybdenum atoms in the clusters have different redox characteristic. Comparing the cyclic voltammograms of the clusters with those of MoCl_5 and complex [Mo(Etdtc)_4][MoCl_6], it was shown that the two peaks at the positive potential region reflect oxidation characteristic of metal-metal bond in the four-molybdenum clusters.
