Electrochemical and Spectroelectrochemical studies of Mixed-Valence Heteropolyanion VMo₁₂O₄₀^n- (n=4,5,6) in Aprotic Media

Department of Chemistry, Jilin University, Changchun 130023

Received Date: 7 March 1997

The mixed-valence heteropolyanion VMo₁₂O₄₀^n- (where n=4,5,6) in aprotic media was investigated by cyclic voltammetry and in-situ FTIR and UV-visible-near-IR spectroelectrochemical methods.The results indicate that the heteropolyanion VMo₁₂O₄₀^3- undergoes three reversible one electron transfer reductions and the mixed-valence heteropolyanion VMo₁₂O₄₀^n- (where n=4,5,6) was formed after electroreduction.The spectra of the aforementioned mixed-valence compounds were characterized by in-situ spectroelectrochemical methods.
