Sr3WO6 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form SrO6 octahedra that share corners with six equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 30-36°. In the second Sr site, Sr(2) is bonded in a 8-coordinate geometry to two equivalent O(1), three equivalent O(2), and three equivalent O(3) atoms. W(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form WO6 octahedra that share corners with six equivalent Sr(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 30-36°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted see-saw-like geometry to one Sr(1), two equivalent Sr(2), and one W(1) atom. In the second O site, O(2) is bonded in a 5-coordinate geometry to one Sr(1), three equivalent Sr(2), and one W(1) atom. In the third O site, O(3) is bonded in a 5-coordinate geometry to one Sr(1), three equivalent Sr(2), and one W(1) atom.

The corner-sharing octahedral tilt angles range from 30-36°. Both Sr(1)-O(1) bond lengths are 2.46 Å. Both Sr(1)-O(2) bond lengths are 2.49 Å. Both Sr(1)-O(3) bond lengths are 2.43 Å. In the second Sr site, Sr(2) is bonded in a 8-coordinate geometry to two equivalent O(1), three equivalent O(2), and three equivalent O(3) atoms. There is one shorter (2.49 Å) and one longer (2.55 Å) Sr(2)-O(1) bond length. There are a spread of Sr(2)-O(2) bond distances ranging from 2.53-3.10 Å. There are a spread of Sr(2)-O(3) bond distances ranging from 2.51-2.90 Å. W(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form WO6 octahedra that share corners with six equivalent Sr(1)O6 octahedra.
