The material described by Li2Cu(WO4)2 crystallizes in the triclinic P-1 space group. Li(1) is bonded to one O(2), one O(3), one O(4), and two equivalent O(1) atoms to form distorted LiO5 trigonal bipyramids that share corners with five equivalent W(1)O6 octahedra,  an edgeedge with one W(1)O6 octahedra, and  an edgeedge with one Li(1)O5 trigonal bipyramid. The corner-sharing octahedral tilt angles range from 42-60°. W(1) is bonded to one O(1), one O(4), two equivalent O(2), and two equivalent O(3) atoms to form distorted WO6 octahedra that share corners with five equivalent Li(1)O5 trigonal bipyramids, edges with two equivalent W(1)O6 octahedra, and  an edgeedge with one Li(1)O5 trigonal bipyramid. Cu(1) is bonded in a distorted square co-planar geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a rectangular see-saw-like geometry to two equivalent Li(1), one W(1), and one Cu(1) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Li(1), two equivalent W(1), and one Cu(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Li(1) and two equivalent W(1) atoms. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to one Li(1), one W(1), and one Cu(1) atom. is represented by the CIF card [CIF]
