Abstract
The mixed-valence heteropolyanion [HAs2Mo18O62](n-)(n = 6, 7, 8, 9) we re investigated by electrochemical and in-situ UV-Vis-Near-IR and FTIR spectroelectrochemical methods in aprotic media, The results indicate that the heteropolyanion [HAs2Mo18O62](5-) with four step one electro n transfer reductions and the mixed-valence heteropolyanions [HAs2Mo18 O62](n-)(n = 6, 7, 8, 9) were formed after electroreduction, The mixed -valence heteropolyanions have IVCT bands in Near-IR spectral region, The characteristic absorption of Mo = O double bond and the Mo-O bridg e bond shift to low wavenumber after electroreduction.
