摘要: 用循环伏安法研究了3种具有相同簇芯、不同配体的四钼簇合物:Mo43-O)2O4Cl2(p=ClC6H4COO)6、Mo4(μs-O)2O4Cl2(p-NHCOCH3C6H4COO)6和Mo43-O)2O4Cl2(o-NHCOCH3m-NO2C6H3-COO)5。结果表明,相同簇芯的簇合物具有十分相似的循环伏安图,峰电势的差异与配体上取代基的电子效应有关。

Abstract: Three kinds of tetranuclear molybdenum clusters with the same cluster core and different ligands were studied by cyclic voltammetry. Their formulae are Mo43-O)2O4Cl2(p-ClC6H4COO)6, Mo43-O)2O4Cl2(p-NHCOCH3C6H4COO)6and Mo43-O)2O4Cl2(o-NHCOCH3m-NO2C6H3COO)6.It is concluded from the experimental results that the clusters with the same cluster core have a very similar cyclic voltammogram, and the differences between the peak potentials are related to the electron effects of the substituents of ligands.
