CdWO4 crystallizes in the monoclinic P2/c space group. W(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form distorted WO6 octahedra that share corners with eight equivalent Cd(1)O6 octahedra and edges with two equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 40-58°. Cd(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form distorted CdO6 octahedra that share corners with eight equivalent W(1)O6 octahedra and edges with two equivalent Cd(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 40-58°. There are two inequivalent O sites. In the first O site, O(2) is bonded in a 3-coordinate geometry to one W(1) and two equivalent Cd(1) atoms. In the second O site, O(1) is bonded in a trigonal planar geometry to two equivalent W(1) and one Cd(1) atom.

The corner-sharing octahedral tilt angles range from 40-58°. Both W(1)-O(2) bond lengths are 1.80 Å. There are two shorter (1.92 Å) and two longer (2.14 Å) W(1)-O(1) bond lengths. Cd(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form distorted CdO6 octahedra that share corners with eight equivalent W(1)O6 octahedra and edges with two equivalent Cd(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 40-58°. Both Cd(1)-O(1) bond lengths are 2.22 Å. There are two shorter (2.28 Å) and two longer (2.40 Å) Cd(1)-O(2) bond lengths. There are two inequivalent O sites. In the first O site, O(2) is bonded in a 3-coordinate geometry to one W(1) and two equivalent Cd(1) atoms.
