The material described by Rb2HgSbI6 crystallizes in the cubic Fm-3m space group. Rb(1) is bonded to twelve equivalent I(1) atoms to form distorted RbI12 cuboctahedra that share corners with twelve equivalent Rb(1)I12 cuboctahedra, faces with six equivalent Rb(1)I12 cuboctahedra, faces with four equivalent Hg(1)I6 octahedra, and faces with four equivalent Sb(1)I6 octahedra. Hg(1) is bonded to six equivalent I(1) atoms to form HgI6 octahedra that share corners with six equivalent Sb(1)I6 octahedra and faces with eight equivalent Rb(1)I12 cuboctahedra. The corner-sharing octahedra are not tilted. Sb(1) is bonded to six equivalent I(1) atoms to form SbI6 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. I(1) is bonded in a linear geometry to four equivalent Rb(1), one Hg(1), and one Sb(1) atom. is represented by the CIF card [CIF]
