LiYW2O8 crystallizes in the monoclinic P2/c space group. Li(1) is bonded in a distorted see-saw-like geometry to two equivalent O(2) and two equivalent O(3) atoms. Y(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms to form distorted YO6 octahedra that share corners with eight equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 47-61°. W(1) is bonded to one O(1), one O(2), two equivalent O(3), and two equivalent O(4) atoms to form distorted WO6 octahedra that share corners with four equivalent Y(1)O6 octahedra and edges with two equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 47-61°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Y(1) and one W(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Li(1), one Y(1), and one W(1) atom. 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 trigonal planar geometry to one Y(1) and two equivalent W(1) atoms.
