Ni(WO4)2 crystallizes in the monoclinic P2/c space group. W(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. Ni(1) is bonded in an octahedral geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one W(1) and one Ni(1) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to two equivalent W(1) and one Ni(1) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one W(1) and one Ni(1) atom. In the fourth O site, O(4) is bonded in a water-like geometry to two equivalent W(1) atoms.
