The structure described by Rb2SnBr6 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 Sn(1)Br6 octahedra. Sn(1) is bonded to six equivalent Br(1) atoms to form SnBr6 octahedra that share faces with eight equivalent Rb(1)Br12 cuboctahedra. Br(1) is bonded to four equivalent Rb(1) and one Sn(1) atom to form a mixture of distorted corner, face, and edge-sharing BrRb4Sn square pyramids. is represented by the CIF card [CIF]
