Abstract
Two new charge transfer salts based on Keggin polyoxoanions, [Hen]2[H2en][PMoVI 11MoVO40]・3.5H2O (1) and [Hpy]4[GeMoVI 12O40]・2H2O (2) (en = ethylenediamine, py = pyridine), have been synthesized and characterized by single crystal X-ray diffraction, elemental analyses, IR spectra, UV/vis spectra, cyclic voltammograms and X-ray photoelectron spectra. The IR spectra and solid reflectance electronic spectra of the title compounds indicate that interactions exist between the polyanions and the organic substrates, which are probably caused by charge transfer.
