There are a spread of Sr–O bond distances ranging from 2.60–3.09 Å. In the second Sr2+ site, Sr2+ is bonded to twelve O2- atoms to form distorted SrO12 cuboctahedra that share corners with twelve SrO12 cuboctahedra, faces with six SrO12 cuboctahedra, faces with four MgO6 octahedra, and faces with four equivalent WO6 octahedra. There are a spread of Sr–O bond distances ranging from 2.60–3.09 Å. In the third Sr2+ site, Sr2+ is bonded to twelve O2- atoms to form distorted SrO12 cuboctahedra that share corners with twelve SrO12 cuboctahedra, faces with six SrO12 cuboctahedra, faces with four MgO6 octahedra, and faces with four WO6 octahedra. There are a spread of Sr–O bond distances ranging from 2.60–3.09 Å.
