PWO5 crystallizes in the orthorhombic Fddd space group. W(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form WO6 octahedra that share corners with two equivalent W(1)O6 octahedra and corners with four equivalent P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 44°. P(1) is bonded to two equivalent O(1) and two equivalent O(3) atoms to form PO4 tetrahedra that share corners with four equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 32-54°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one W(1) and one P(1) atom. In the second O site, O(3) is bonded in a bent 120 degrees geometry to one W(1) and one P(1) atom. In the third O site, O(2) is bonded in a bent 150 degrees geometry to two equivalent W(1) atoms.
