Syntheses and IR Spectra of New Charge Transfer Polyoxometalates

Eleven new charge transfer polyoxometalates have been synthesized from four heteropoly acids with Dawson structure and three heteroaromatic compounds.IR spectra studies indicate that the Dawson structure of the heteropolyanion has a little change after a charge transfer polyoxometalate was formed,and that charge transfer interaction is present between organic donor and heteropolyanion.
