Sr3WO6 is Ilmenite-like structured and crystallizes in the trigonal R-3 space group. Sr(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form distorted SrO6 pentagonal pyramids that share  a cornercorner with one W(1)O6 octahedra,  a cornercorner with one W(2)O6 octahedra, corners with four equivalent Sr(1)O6 pentagonal pyramids,  an edgeedge with one W(1)O6 octahedra,  an edgeedge with one W(2)O6 octahedra, and edges with four equivalent Sr(1)O6 pentagonal pyramids. The corner-sharing octahedral tilt angles range from 28-36°. There are two inequivalent W sites. In the first W site, W(1) is bonded to six equivalent O(2) atoms to form WO6 octahedra that share corners with six equivalent Sr(1)O6 pentagonal pyramids and edges with six equivalent Sr(1)O6 pentagonal pyramids. In the second W site, W(2) is bonded to six equivalent O(1) atoms to form WO6 octahedra that share corners with six equivalent Sr(1)O6 pentagonal pyramids and edges with six equivalent Sr(1)O6 pentagonal pyramids. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Sr(1) and one W(2) atom to form a mixture of distorted corner and edge-sharing OSr3W trigonal pyramids. In the second O site, O(2) is bonded in a distorted see-saw-like geometry to three equivalent Sr(1) and one W(1) atom.

The corner-sharing octahedral tilt angles range from 28-36°. There are a spread of Sr(1)-O(1) bond distances ranging from 2.46-2.60 Å. There is one shorter (2.48 Å) and two longer (2.50 Å) Sr(1)-O(2) bond lengths. There are two inequivalent W sites. In the first W site, W(1) is bonded to six equivalent O(2) atoms to form WO6 octahedra that share corners with six equivalent Sr(1)O6 pentagonal pyramids and edges with six equivalent Sr(1)O6 pentagonal pyramids. All W(1)-O(2) bond lengths are 1.94 Å. In the second W site, W(2) is bonded to six equivalent O(1) atoms to form WO6 octahedra that share corners with six equivalent Sr(1)O6 pentagonal pyramids and edges with six equivalent Sr(1)O6 pentagonal pyramids. All W(2)-O(1) bond lengths are 1.95 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Sr(1) and one W(2) atom to form a mixture of distorted corner and edge-sharing OSr3W trigonal pyramids. In the second O site, O(2) is bonded in a distorted see-saw-like geometry to three equivalent Sr(1) and one W(1) atom.
