Cr(WO4)2 crystallizes in the monoclinic P2/c space group. W(1) is bonded to one O(1), one O(3), two equivalent O(2), and two equivalent O(4) atoms to form distorted WO6 octahedra that share corners with four equivalent Cr(1)O6 octahedra and edges with two equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 38-56°. Cr(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form CrO6 octahedra that share corners with eight equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 38-56°. 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 Cr(1) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to two equivalent W(1) and one Cr(1) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one W(1) and one Cr(1) atom. In the fourth O site, O(4) is bonded in a water-like geometry to two equivalent W(1) atoms.
