Cs2RbScF6 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 Sc(1)F6 octahedra. Rb(1) is bonded to six equivalent F(1) atoms to form RbF6 octahedra that share corners with six equivalent Sc(1)F6 octahedra and faces with eight equivalent Cs(1)F12 cuboctahedra. The corner-sharing octahedra are not tilted. Sc(1) is bonded to six equivalent F(1) atoms to form ScF6 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 2-coordinate geometry to four equivalent Cs(1), one Rb(1), and one Sc(1) atom.
