Sr2ZnWO6 is Copper structured and crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three Sr2ZnWO6 clusters. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a distorted rectangular see-saw-like geometry to one W(1) and three equivalent O(1) atoms. The Sr(1)-W(1) bond length is 0.14 Å. All Sr(1)-O(1) bond lengths are 0.32 Å. In the second Sr site, Sr(2) is bonded in a distorted linear geometry to one W(1) and one Zn(1) atom. The Sr(2)-W(1) bond length is 0.14 Å. The Sr(2)-Zn(1) bond length is 0.14 Å. W(1) is bonded in a linear geometry to one Sr(1) and one Sr(2) atom. Zn(1) is bonded in a distorted tetrahedral geometry to one Sr(2) and three equivalent O(2) atoms. All Zn(1)-O(2) bond lengths are 0.25 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one Sr(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to one Zn(1) atom.
