Abstract

The iron phosphate, Fe(H 2 PO 4 ) 3 , was synthesized through a precipitation route by means of acidic media. As the compound is highly hygroscopic, the structure was solved ab initio by powder X-ray diffraction under nitrogen flow at room temperature and 200 °C. This phase is antiferromagnetic below 30 K . It converts into Fe(PO 3 ) 3 at 550 °C, after dehydration. Electrochemical characterizations, performed on the last compound, show irreversible decomposition into metallic iron.
