The material structure described by LiW2P3O13 crystallizes in the monoclinic C2/c space group. Li(1) is bonded in a linear geometry to two equivalent O(6) atoms. W(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form distorted WO6 octahedra that share corners with two equivalent P(1)O4 tetrahedra and corners with three equivalent P(2)O4 tetrahedra. There are two inequivalent P sites. In the first P site, P(1) is bonded to two equivalent O(2) and two equivalent O(4) atoms to form PO4 tetrahedra that share corners with four equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 40-50°. In the second P site, P(2) is bonded to one O(1), one O(3), one O(6), and one O(7) 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 42-55°. There are seven inequivalent O sites. In the first O site, O(7) is bonded in a bent 120 degrees geometry to two equivalent P(2) atoms. In the second O site, O(1) is bonded in a distorted single-bond geometry to one W(1) and one P(2) atom. In the third O site, O(2) is bonded in a distorted bent 150 degrees geometry to one W(1) and one P(1) atom. In the fourth O site, O(3) is bonded in a distorted bent 150 degrees geometry to one W(1) and one P(2) atom. In the fifth O site, O(4) is bonded in a distorted bent 120 degrees geometry to one W(1) and one P(1) atom. In the sixth O site, O(5) is bonded in a single-bond geometry to one W(1) atom. In the seventh O site, O(6) is bonded in a 3-coordinate geometry to one Li(1), one W(1), and one P(2) atom. is represented by the CIF card [CIF]
