摘要：

We report the synthesis of thorium diphosphate ThP2O7 and its study by Raman spectroscopy and Rietveld analysis. This Compound has been found to be closely related to the zirconium diphosphate type, with space group Pa-3 and a = 8.7601(3) angstrom. No superstructure was observed. The metastability of ThP2O7 appears to stem from the six-fold oxygen environment of Th-IV, a unique case in the structural chemistry of this cation. (C) 2008 Elsevier Inc. All rights reserved.
