(Sr3(WO4)2)2O2 is Indium-derived structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of one 7782-44-7 molecule and one Sr3(WO4)2 cluster. In the Sr3(WO4)2 cluster, there are three inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a distorted single-bond geometry to one Sr(2) and one O(6) atom. The Sr(1)-Sr(2) bond length is 0.35 Å. The Sr(1)-O(6) bond length is 2.91 Å. In the second Sr site, Sr(2) is bonded in a 1-coordinate geometry to one Sr(1), one O(7), and one O(9) atom. The Sr(2)-O(7) bond length is 0.43 Å. The Sr(2)-O(9) bond length is 0.66 Å. In the third Sr site, Sr(3) is bonded in a distorted single-bond geometry to one O(1), one O(3), and one O(7) atom. The Sr(3)-O(1) bond length is 2.57 Å. The Sr(3)-O(3) bond length is 2.43 Å. The Sr(3)-O(7) bond length is 1.35 Å. There are two inequivalent W sites. In the first W site, W(1) is bonded in a distorted single-bond geometry to one W(2) and one O(1) atom. The W(1)-W(2) bond length is 0.41 Å. The W(1)-O(1) bond length is 2.29 Å. In the second W site, W(2) is bonded in a linear geometry to one W(1) and one W(2) atom. The W(2)-W(2) bond length is 0.27 Å. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Sr(3), one W(1), and one O(4) atom. The O(1)-O(4) bond length is 1.38 Å. In the second O site, O(2) is bonded in a single-bond geometry to one O(8) atom. The O(2)-O(8) bond length is 0.88 Å. In the third O site, O(3) is bonded in a single-bond geometry to one Sr(3) atom. In the fourth O site, O(4) is bonded in a 2-coordinate geometry to one O(1) and one O(8) atom. The O(4)-O(8) bond length is 0.77 Å. In the fifth O site, O(6) is bonded in a single-bond geometry to one Sr(1) atom. In the sixth O site, O(7) is bonded in a single-bond geometry to one Sr(2) and one Sr(3) atom. In the seventh O site, O(8) is bonded in a water-like geometry to one O(2) and one O(4) atom. In the eighth O site, O(9) is bonded in a single-bond geometry to one Sr(2) atom.
