The compound described by Zn(WO2)2 is Spinel-like structured and crystallizes in the trigonal R3m space group. There are two inequivalent W sites. In the first W site, W(1) is bonded to one O(2) and three equivalent O(1) atoms to form distorted WO4 trigonal pyramids that share corners with three equivalent Zn(2)O6 octahedra and corners with nine equivalent W(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 43-66°. In the second W site, W(2) is bonded to one O(2), one O(3), two equivalent O(1), and two equivalent O(4) atoms to form WO6 octahedra that share corners with three equivalent Zn(1)O4 tetrahedra, corners with three equivalent W(1)O4 trigonal pyramids, edges with two equivalent Zn(2)O6 octahedra, and edges with four equivalent W(2)O6 octahedra. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded to one O(3) and three equivalent O(4) atoms to form ZnO4 tetrahedra that share corners with three equivalent Zn(2)O6 octahedra and corners with nine equivalent W(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 52-59°. In the second Zn site, Zn(2) is bonded to three equivalent O(1) and three equivalent O(4) atoms to form ZnO6 octahedra that share corners with three equivalent Zn(1)O4 tetrahedra, corners with three equivalent W(1)O4 trigonal pyramids, and edges with six equivalent W(2)O6 octahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded in a rectangular see-saw-like geometry to one W(1), two equivalent W(2), and one Zn(2) atom. In the second O site, O(2) is bonded to one W(1) and three equivalent W(2) atoms to form distorted corner-sharing OW4 tetrahedra. In the third O site, O(3) is bonded to three equivalent W(2) and one Zn(1) atom to form distorted corner-sharing OZnW3 trigonal pyramids. In the fourth O site, O(4) is bonded in a rectangular see-saw-like geometry to two equivalent W(2), one Zn(1), and one Zn(2) atom. is represented by the CIF file [CIF]
