N2 - Sealed tube reactions of WO3, P2O5, and W metal at 1250°C give crystals of WPO5. The compound was characterized by single-crystal X-ray diffraction data with a = 11.174(3), b = 6.550(2), c = 5.228(1) Å, Z = 4, in the space group Pna21. The structure was refined to R(F) = 0.0273 and Rw = 0.0268 for 547 independent reflections with I > 3.0 σ(I). This compound, which contains only W5+, is composed of corner-sharing WO6 octahedra and PO4 tetrahedra. Pentagonal tunnels along the c-axis are formed by the edges of three octahedra and two tetrahedra. The framework can also be described as built up from ReO3-type slabs which are connected through phosphate groups. It corresponds to the second member (m = 2) of the monophosphate tungsten bronze series (WO3)2m(PO2)4.
