V(Ⅳ) and V(Ⅴ) containing mixed - valence heteropolytungstogermanates have been prepared by controlled potential reduction of corresponding GeW9V3O407-, their electronic spectra have been recorded. The ESR spectra of one- electron- reduced anions in solution at 340K consist of more than 40 equally spaced lines, showing that the three VO6 octahedra in both α - and β-forms are corner - shared and one of the bridging oxygen atoms is protonated at pH 4.7.
