The compound described by Li2WP2O8 crystallizes in the trigonal P-3 space group. Li(1) is bonded in a rectangular see-saw-like geometry to one O(2) and three equivalent O(1) atoms. W(1) is bonded to six equivalent O(1) atoms to form WO6 octahedra that share corners with six equivalent P(1)O4 tetrahedra. P(1) is bonded to one O(2) and three equivalent O(1) atoms to form PO4 tetrahedra that share corners with three equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles are 47°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Li(1), one W(1), and one P(1) atom. In the second O site, O(2) is bonded in a linear geometry to one Li(1) and one P(1) atom. is represented by the CIF card [CIF]
