The structure described by Zn(WO2)4 crystallizes in the trigonal R-3m space group. There are two inequivalent W sites. In the first W site, W(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form WO6 octahedra that share edges with two equivalent W(2)O6 octahedra, edges with two equivalent Zn(1)O6 octahedra, and edges with four equivalent W(1)O6 octahedra. In the second W site, W(2) is bonded to six equivalent O(1) atoms to form WO6 octahedra that share corners with six equivalent Zn(1)O6 octahedra and edges with six equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles are 8°. Zn(1) is bonded to six equivalent O(1) atoms to form ZnO6 octahedra that share corners with six equivalent W(2)O6 octahedra and edges with six equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles are 8°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a rectangular see-saw-like geometry to one W(2), two equivalent W(1), and one Zn(1) atom. In the second O site, O(2) is bonded in a trigonal non-coplanar geometry to three equivalent W(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
