The crystal structure described by Ni(WO4)2 crystallizes in the triclinic P-1 space group. W(1) is bonded to one O(2), one O(4), two equivalent O(1), and two equivalent O(3) 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 28-53°. Ni(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms to form NiO6 octahedra that share corners with eight equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 28-53°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to two equivalent W(1) and one Ni(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one W(1) and one Ni(1) atom. In the third O site, O(3) is bonded in a water-like geometry to two equivalent W(1) atoms. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to one W(1) and one Ni(1) atom. is represented by the CIF file [CIF]
