Rb2NaScI6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. Rb(1) is bonded to twelve equivalent I(1) atoms to form RbI12 cuboctahedra that share corners with twelve equivalent Rb(1)I12 cuboctahedra, faces with six equivalent Rb(1)I12 cuboctahedra, faces with four equivalent Na(1)I6 octahedra, and faces with four equivalent Sc(1)I6 octahedra. Na(1) is bonded to six equivalent I(1) atoms to form NaI6 octahedra that share corners with six equivalent Sc(1)I6 octahedra and faces with eight equivalent Rb(1)I12 cuboctahedra. The corner-sharing octahedra are not tilted. Sc(1) is bonded to six equivalent I(1) atoms to form ScI6 octahedra that share corners with six equivalent Na(1)I6 octahedra and faces with eight equivalent Rb(1)I12 cuboctahedra. The corner-sharing octahedra are not tilted. I(1) is bonded in a linear geometry to four equivalent Rb(1), one Na(1), and one Sc(1) atom.
