Cs2RbAuF6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. Cs(1) is bonded to twelve equivalent F(1) atoms to form CsF12 cuboctahedra that share corners with twelve equivalent Cs(1)F12 cuboctahedra, faces with six equivalent Cs(1)F12 cuboctahedra, faces with four equivalent Rb(1)F6 octahedra, and faces with four equivalent Au(1)F6 octahedra. Rb(1) is bonded to six equivalent F(1) atoms to form RbF6 octahedra that share corners with six equivalent Au(1)F6 octahedra and faces with eight equivalent Cs(1)F12 cuboctahedra. The corner-sharing octahedra are not tilted. Au(1) is bonded to six equivalent F(1) atoms to form AuF6 octahedra that share corners with six equivalent Rb(1)F6 octahedra and faces with eight equivalent Cs(1)F12 cuboctahedra. The corner-sharing octahedra are not tilted. F(1) is bonded in a distorted linear geometry to four equivalent Cs(1), one Rb(1), and one Au(1) atom.
