CuWO4 crystallizes in the monoclinic P2/c space group. W(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form distorted WO6 octahedra that share corners with eight equivalent Cu(1)O6 octahedra and edges with two equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 42-57°. Cu(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form CuO6 octahedra that share corners with eight equivalent W(1)O6 octahedra and edges with two equivalent Cu(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 42-57°. There are two inequivalent O sites. In the first O site, O(2) is bonded in a trigonal planar geometry to two equivalent W(1) and one Cu(1) atom. In the second O site, O(1) is bonded in a 3-coordinate geometry to one W(1) and two equivalent Cu(1) atoms.
