The crystal structure described by LiNi(WO4)2 crystallizes in the triclinic P1 space group. Li(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(3), one O(4), one O(6), and one O(8) atom. There are two inequivalent W sites. In the first W site, W(1) is bonded to one O(1), one O(3), one O(4), one O(5), one O(6), and one O(8) atom to form distorted WO6 octahedra that share corners with four equivalent Ni(1)O6 octahedra and edges with two equivalent W(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 40-55°. In the second W site, W(2) is bonded to one O(2), one O(3), one O(5), one O(6), one O(7), and one O(8) atom 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 34-54°. Ni(1) is bonded to one O(1), one O(2), one O(4), one O(5), one O(7), and one O(8) atom to form NiO6 octahedra that share corners with four equivalent W(1)O6 octahedra and corners with four equivalent W(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 34-55°. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one Li(1), one W(1), and one Ni(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Li(1), one W(2), and one Ni(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Li(1), one W(1), and one W(2) atom. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to one Li(1), one W(1), and one Ni(1) atom. In the fifth O site, O(5) is bonded in a trigonal planar geometry to one W(1), one W(2), and one Ni(1) atom. In the sixth O site, O(6) is bonded in a distorted T-shaped geometry to one Li(1), one W(1), and one W(2) atom. In the seventh O site, O(7) is bonded in a bent 150 degrees geometry to one W(2) and one Ni(1) atom. In the eighth O site, O(8) is bonded in a trigonal pyramidal geometry to one Li(1), one W(1), one W(2), and one Ni(1) atom. is represented by the CIF file [CIF]
