The compound described by LiWP4O12 crystallizes in the monoclinic C2/c space group. Li(1) is bonded to two equivalent O(2), two equivalent O(4), and two equivalent O(5) atoms to form distorted LiO6 octahedra that share corners with two equivalent P(1)O4 tetrahedra, corners with four equivalent P(2)O4 tetrahedra, and edges with two equivalent W(1)O6 octahedra. W(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(5) atoms to form WO6 octahedra that share corners with two equivalent P(2)O4 tetrahedra, corners with four equivalent P(1)O4 tetrahedra, and edges with two equivalent Li(1)O6 octahedra. There are two inequivalent P sites. In the first P site, P(1) is bonded to one O(1), one O(3), one O(5), and one O(6) atom to form PO4 tetrahedra that share  a cornercorner with one Li(1)O6 octahedra, corners with two equivalent W(1)O6 octahedra, and corners with two equivalent P(2)O4 tetrahedra.

The corner-sharing octahedral tilt angles range from 24-59°. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 150 degrees geometry to one W(1) and one P(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Li(1), one W(1), and one P(2) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one P(1) and one P(2) atom. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to one Li(1) and one P(2) atom. In the fifth O site, O(5) is bonded in a distorted trigonal planar geometry to one Li(1), one W(1), and one P(1) atom.
