The structure described by Li2Ni(WO4)2 crystallizes in the triclinic P-1 space group. Li(1) is bonded in a 6-coordinate geometry to one O(1), one O(3), two equivalent O(2), and two equivalent O(4) atoms. 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 Ni(1)O6 octahedra and edges with two equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 41-55°. Ni(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form NiO6 octahedra that share corners with eight equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 41-55°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Li(1), one W(1), and one Ni(1) atom. In the second O site, O(2) is bonded to two equivalent Li(1), one W(1), and one Ni(1) atom to form distorted OLi2NiW trigonal pyramids that share  a cornercorner with one O(2)Li2NiW trigonal pyramid, corners with two equivalent O(3)LiNiW2 trigonal pyramids,  an edgeedge with one O(2)Li2NiW trigonal pyramid, and edges with two equivalent O(3)LiNiW2 trigonal pyramids. In the third O site, O(3) is bonded to one Li(1), two equivalent W(1), and one Ni(1) atom to form distorted OLiNiW2 trigonal pyramids that share  a cornercorner with one O(3)LiNiW2 trigonal pyramid, corners with two equivalent O(2)Li2NiW trigonal pyramids,  an edgeedge with one O(3)LiNiW2 trigonal pyramid, and edges with two equivalent O(2)Li2NiW trigonal pyramids. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to two equivalent Li(1) and two equivalent W(1) atoms. is represented by the CIF file [CIF]
