Cs2ScHgCl6 crystallizes in the cubic Fm-3m space group. Cs(1) is bonded to twelve equivalent Cl(1) atoms to form CsCl12 cuboctahedra that share corners with twelve equivalent Cs(1)Cl12 cuboctahedra, faces with six equivalent Cs(1)Cl12 cuboctahedra, faces with four equivalent Sc(1)Cl6 octahedra, and faces with four equivalent Hg(1)Cl6 octahedra. Sc(1) is bonded to six equivalent Cl(1) atoms to form ScCl6 octahedra that share corners with six equivalent Hg(1)Cl6 octahedra and faces with eight equivalent Cs(1)Cl12 cuboctahedra. The corner-sharing octahedra are not tilted. Hg(1) is bonded to six equivalent Cl(1) atoms to form HgCl6 octahedra that share corners with six equivalent Sc(1)Cl6 octahedra and faces with eight equivalent Cs(1)Cl12 cuboctahedra. The corner-sharing octahedra are not tilted. Cl(1) is bonded in a 6-coordinate geometry to four equivalent Cs(1), one Sc(1), and one Hg(1) atom.
