Rb2SmAuCl6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. Rb(1) is bonded to twelve equivalent Cl(1) atoms to form RbCl12 cuboctahedra that share corners with twelve equivalent Rb(1)Cl12 cuboctahedra, faces with six equivalent Rb(1)Cl12 cuboctahedra, faces with four equivalent Sm(1)Cl6 octahedra, and faces with four equivalent Au(1)Cl6 octahedra. Sm(1) is bonded to six equivalent Cl(1) atoms to form SmCl6 octahedra that share corners with six equivalent Au(1)Cl6 octahedra and faces with eight equivalent Rb(1)Cl12 cuboctahedra. The corner-sharing octahedra are not tilted. Au(1) is bonded to six equivalent Cl(1) atoms to form AuCl6 octahedra that share corners with six equivalent Sm(1)Cl6 octahedra and faces with eight equivalent Rb(1)Cl12 cuboctahedra. The corner-sharing octahedra are not tilted. Cl(1) is bonded in a 2-coordinate geometry to four equivalent Rb(1), one Sm(1), and one Au(1) atom.
