✦ Synopsis

We have reported previously [l] on the chemical and electrochemical syntheses of a binuclear mixedvalence vanadium(IV,V) complex, [(V'"OQz)-O-(V"-0Q2)]-(Q-= 8-quinolinol anion). This complex undergoes a reversible one electron per dimer oxidation in acetonitrile. The oxidation product is stable and its solution exhibits a cyclic voltammogram similar to that of VO(OH)Qz. Due to the bond breaking that would be necessary to form VO(OH)Qz, we suggested that the actual oxidation product mi the vanadium(V,V) dimer, (VvOQz)-0-(V #h t be OQz). This dimer can in fact be formed from the monomer by heating [2,3] : 2VO(OH)Qz s
