The structure described by Rb2SbBr6 crystallizes in the cubic Fm-3m space group. Rb(1) is bonded to twelve equivalent Br(1) atoms to form RbBr12 cuboctahedra that share corners with twelve equivalent Rb(1)Br12 cuboctahedra, faces with six equivalent Rb(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 Rb(1)Br12 cuboctahedra. Br(1) is bonded to four equivalent Rb(1) and one Sb(1) atom to form a mixture of distorted edge, face, and corner-sharing BrRb4Sb square pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
