摘    要:用循环伏安法研究了[Mo_3OCl_6(O_2CR)_3]-(其中R=CH_3,H,CH_2Cl)系列三核钼簇合物在CH_3CN和DMF溶剂中的电化学行为,并用差热-热重手段研究了它们的热稳定性和热分解过程的可能机理。结果表明在不同溶剂中它们有相似的二对氧化还原峰,而且在同一溶剂中随着R基团吸电子能力的增强,相应的第一氧化还原电位值向正向移动。当R=CH_3,H时,它们的起始分解温度分别为265℃和210℃,即同样随着R基团吸电子能力的增强,起始分解温度降低。

关 键 词:三核钼簇合物,电化学,热化学

Abstract:Electrochemical behaviors for a series of trinuclear molybdenum cluster compounds[Mo_3OCl_6 (O_2CR)_3) ̄-in acetonitrile and dimethylformide solvents were studied with cyclic voltammetry in this paper.Two redox peaks were assigned. The effect of changing R radical of carboxyl on the redox characteristics of these cluster compounds was discussed preliminarily.In addition, their thermal stability and the thermolytic behavior in nitrogen atmosphere were investigated by DTA-TG method. The effect of changing R radical on the thermal stability of the cluster compounds was discussed.Their possible thermolytic mechanism was also offered.
Keywords:trinuclear molybdenum cluster compound  electrochemistry  thermochemistry
