Li3(WO3)8 crystallizes in the orthorhombic Pmmm space group. There are three inequivalent Li sites. In the first Li site, Li(1) is bonded in a square co-planar geometry to four equivalent O(3) atoms. In the second Li site, Li(2) is bonded in a square co-planar geometry to four equivalent O(4) atoms. In the third Li site, Li(3) is bonded in a square co-planar geometry to four 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 corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 26-31°. There are six inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to two equivalent W(1) atoms. In the second O site, O(2) is bonded in a bent 150 degrees geometry to two equivalent W(1) atoms. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Li(1) and two equivalent W(1) atoms. In the fourth O site, O(4) is bonded in a distorted trigonal non-coplanar geometry to one Li(2) and two equivalent W(1) atoms. In the fifth O site, O(5) is bonded in a bent 150 degrees geometry to two equivalent W(1) atoms. In the sixth O site, O(6) is bonded in a distorted trigonal non-coplanar geometry to one Li(3) and two equivalent W(1) atoms.
