Dodecatungstophosphoric acid hexahydrate H3PW12O40.6H(2)O crystal structure has been investigated by neutron powder diffraction (NPD) at different temperatures in the 10-358 K range. A nonconvergent reversible phase transition has been noticed at about 320 K. This transition is associated with a change in dynamic equilibrium of hydrate species and partial reduction/oxidation (redox) W6+ LT ---- GT (5+). Expressive structure changes lie in the P-O bonding inside Keggins anion and the H5O2+ conformational angle. (C) 2002 Published by Elsevier Science B.V.
