Rb2ScHgI6 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 Sc(1)I6 octahedra, and faces with four equivalent Hg(1)I6 octahedra. Sc(1) is bonded to six equivalent I(1) atoms to form ScI6 octahedra that share corners with six equivalent Hg(1)I6 octahedra and faces with eight equivalent Rb(1)I12 cuboctahedra. The corner-sharing octahedra are not tilted. Hg(1) is bonded to six equivalent I(1) atoms to form HgI6 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. I(1) is bonded in a distorted linear geometry to four equivalent Rb(1), one Sc(1), and one Hg(1) atom.
