Abstract: The intensity of Fe2p3/2 satellite peaks and the binding energies of Fe2p3/2 and O1s. for five het-eropolyanions were determined. The IR spectra and the magnetic susceptibility in these anions were obtained. The spin state of Fe in the anions was deduced. The d-pπ bond of Fe-O-Fe bridge in (SiFeW11)2O was identified. The effects of the frame- and center hetero-atoms on the electron cloud density of iron in the anions are discussed.
