There are a spread of Ba–O bond distances ranging from 2.81–3.24 Å. In the second Ba2+ site, Ba2+ is bonded to twelve O2- atoms to form distorted BaO12 cuboctahedra that share corners with twelve BaO12 cuboctahedra, faces with three equivalent BaO12 cuboctahedra, faces with four CaO6 octahedra, and faces with four WO6 octahedra. There are a spread of Ba–O bond distances ranging from 2.80–3.23 Å.
