Abstract
The preparation of a new acid lanthanide diphosphate is reported. The acid praseodymium diphosphate, obtained as a trihydrate salt, is investigated by chemical analysis, X-ray powder diffraction and IR spectroscopy. The study of the thermal behavior of HPrP2O7. 3H(2)O shows that its dehydration begi ns at 367 K. A scheme of its decomposition is proposed.
