The material described by WP2O8 crystallizes in the monoclinic P2_1/c space group. W(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms to form WO6 octahedra that share corners with six equivalent P(1)O4 tetrahedra. P(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form PO4 tetrahedra that share corners with three equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 36-40°. There are four 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(2) is bonded in a bent 150 degrees geometry to one W(1) and one P(1) atom. In the third O site, O(3) is bonded in a single-bond geometry to one P(1) atom. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to one W(1) and one P(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
