摘要：

Sodium yttrium diphosphate crystallizes in the noncentrosymmetric space group P2(1). The structure consists of corner-sharing YO6 octahedra and P2O7 groups forming an alternate stacking of octahedral and phosphate layers. The framework delimits intersecting tunnels where the Na+ cations are located. The P2O7 groups show a nearly staggered configuration intermediate between that in KYP2O7 [Hamady, Zid & Jouini (1994). J. Solid State Chem. 113, 120-124] and that in alpha-NaTiP2O7 [Leclaire, Benmoussa, Borel, Grandin & Raveau (1988). J. Solid State Chem. 77, 299-305].
