Cs2SbBr6 crystallizes in the cubic Fm-3m space group. Cs(1) is bonded to twelve equivalent Br(1) atoms to form CsBr12 cuboctahedra that share corners with twelve equivalent Cs(1)Br12 cuboctahedra, faces with six equivalent Cs(1)Br12 cuboctahedra, and faces with four equivalent Sb(1)Br6 octahedra. Sb(1) is bonded to six equivalent Br(1) atoms to form SbBr6 octahedra that share faces with eight equivalent Cs(1)Br12 cuboctahedra. Br(1) is bonded to four equivalent Cs(1) and one Sb(1) atom to form a mixture of distorted face, corner, and edge-sharing BrCs4Sb square pyramids.
