PWO5 crystallizes in the triclinic P-1 space group. There are two inequivalent W sites. In the first W site, W(1) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(5) atoms to form WO6 octahedra that share corners with two equivalent W(2)O6 octahedra and corners with four equivalent P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 31°. In the second W site, W(2) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(4) 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 31°. P(1) is bonded to one O(1), one O(2), one O(4), and one O(5) atom to form PO4 tetrahedra that share corners with two equivalent W(1)O6 octahedra and corners with two equivalent W(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 26-46°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to one W(1) and one P(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one W(2) and one P(1) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one W(1) and one W(2) atom. In the fourth O site, O(4) is bonded in a distorted bent 150 degrees geometry to one W(2) and one P(1) atom. In the fifth O site, O(5) is bonded in a bent 150 degrees geometry to one W(1) and one P(1) atom.
