Sr2ZnWO6 crystallizes in the tetragonal I4/m space group. Sr(1) is bonded in a 12-coordinate geometry to four equivalent O(2) and eight equivalent O(1) atoms. W(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form WO6 octahedra that share corners with six equivalent Zn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-20°. Zn(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form ZnO6 octahedra that share corners with six equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-20°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to four equivalent Sr(1), one W(1), and one Zn(1) atom. In the second O site, O(2) is bonded to four equivalent Sr(1), one W(1), and one Zn(1) atom to form a mixture of distorted corner and edge-sharing OSr4ZnW octahedra. The corner-sharing octahedral tilt angles range from 0-4°.
Sr2ZnWO6 crystallizes in the tetragonal I4/m space group. Sr(1) is bonded in a 12-coordinate geometry to four equivalent O(2) and eight equivalent O(1) atoms. All Sr(1)-O(2) bond lengths are 2.83 Å. There are four shorter (2.62 Å) and four longer (3.12 Å) Sr(1)-O(1) bond lengths. W(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form WO6 octahedra that share corners with six equivalent Zn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-20°. Both W(1)-O(2) bond lengths are 1.95 Å. All W(1)-O(1) bond lengths are 1.95 Å. Zn(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form ZnO6 octahedra that share corners with six equivalent W(1)O6 octahedra.
