The structure described by WP2O8 crystallizes in the orthorhombic P2_12_12_1 space group. W(1) is bonded to one O(1), one O(2), one O(4), one O(6), one O(7), and one O(8) atom to form WO6 octahedra that share corners with two equivalent P(2)O4 tetrahedra and corners with three equivalent P(1)O4 tetrahedra. There are two inequivalent P sites. In the first P site, 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 three equivalent W(1)O6 octahedra and  a cornercorner with one P(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 3-30°. In the second P site, P(2) is bonded to one O(3), one O(5), one O(7), and one O(8) atom to form PO4 tetrahedra that share corners with two equivalent W(1)O6 octahedra and  a cornercorner with one P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 32°. There are eight 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(2) atom. In the fourth O site, O(4) is bonded in a linear geometry to one W(1) and one P(1) atom. In the fifth O site, O(5) is bonded in a bent 120 degrees geometry to one P(1) and one P(2) atom. In the sixth O site, O(6) is bonded in a single-bond geometry to one W(1) atom. In the seventh O site, O(7) is bonded in a bent 150 degrees geometry to one W(1) and one P(2) atom. In the eighth O site, O(8) is bonded in a bent 150 degrees geometry to one W(1) and one P(2) atom. is represented by the CIF file [CIF]
