Abstract: Heteropoly molybdotungstophosphoric acids (salts) with formula Ln-PMo6W6O40·xH2O (Ln=La, Ce, Pr, Nd) and ZnHP Mo6 W6O40·xH2O were prepared and characterized by elemental analysis, IR, UV spectrometry, and x-ray diffraction.The thermal stabilities of the compounds were as follows:solid acids>rareearth salts>Zn salt.The mechanism of reduction of the heteropolyanion in aqueous solution was proposed.

Key words: heter opoly compounds, Keggin structure, heteropoly molybdotungstophosphotic Acids, preparation properpics
