In the first Ba2+ site, Ba2+ is bonded to six Sb+2.67- atoms to form BaSb6 octahedra that share corners with six equivalent BaSb7 pentagonal bipyramids, corners with seven CdSb4 tetrahedra, edges with four equivalent BaSb6 octahedra, an edgeedge with one BaSb7 pentagonal bipyramid, edges with five CdSb4 tetrahedra, and a faceface with one BaSb7 pentagonal bipyramid. There are a spread of Ba–Sb bond distances ranging from 3.50–3.57 Å. In the second Ba2+ site, Ba2+ is bonded to seven Sb+2.67- atoms to form BaSb7 pentagonal bipyramids that share corners with six equivalent BaSb6 octahedra, corners with seven CdSb4 tetrahedra, an edgeedge with one BaSb6 octahedra, edges with four equivalent BaSb7 pentagonal bipyramids, edges with three CdSb4 tetrahedra, a faceface with one BaSb6 octahedra, and faces with three equivalent BaSb7 pentagonal bipyramids. The corner-sharing octahedra tilt angles range from 36–49°. There are a spread of Ba–Sb bond distances ranging from 3.59–3.78 Å. There are two inequivalent Cd2+ sites.
