Effect of Some Ligands on Oxidation-Reduction Characteristics of Tetranuclear Molybdenum Clusters

Abstract

Abstract: Three kinds of tetranuclear molybdenum clusters with the same cluster core and different ligands were studied by cyclic voltammetry. Their formulae are Mo₄(μ₃-O)₂O₄Cl₂(p-ClC₆H₄COO)₆, Mo₄(μ₃-O)₂O₄Cl₂(p-NHCOCH₃C₆H₄COO)₆and Mo₄(μ₃-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.
