The crystal structure of ![[alpha]](/logos/entities/alpha_rmgif.gif)
-Sr2P2O7, distrontium diphosphate, has been refined by X-ray diffraction using single crystals grown from a SrLiPO4-P2O5 melt cooled between 1323 and 1073 K. The fully anisotropic refinement confirms the centrosymmetric Pnma space group, but also reveals a strong anisotropy along the b direction for two oxygen atoms. This anisotropy suggests atomic scale disorder associated with the local loss of mirror symmetry and the formation of a noncentrosymmetric structural arrangement.
