Tetrabutylammonium salts of the mixed heteropoly molybdovanadate(V) anions, [H<SUB><I>x</I>−1</SUB>V(V<I><SUB>x</SUB></I>Mo<SUB>12−<I>x</I></SUB>)O<SUB>40</SUB>]<SUP>4−</SUP> (<I>x</I>=1–3) were prepared from a Mo(VI)–V(V)–CH<SUB>3</SUB>CN system at room temperature. These mixed heteropoly anions were distinguished by their voltammetric behavior; the anions with <I>x</I>=1, 2, and 3 were electroreduced by one-, two-, and three-electrons due to the peripheral V atoms at a glassy carbon electrode. The spectroscopic properties were also reported. Their formation conditions were compared with those of 12-molybdovanadate (V), [VMo<SUB>12</SUB>O<SUB>40</SUB>]<SUP>3−</SUP>, especially regarding the concentrations of Mo(VI), V(V), acid, and organic solvents, the nature of organic solvents, and the ionic strength of the system. It should be emphasized that the 12-molybdovanadate(V) and mixed molybdovanadate(V) complexes are not formed in the absence of organic solvents.
