CsRb2AlCl6 crystallizes in the cubic Fm-3m space group. Cs(1) is bonded to six equivalent Cl(1) atoms to form CsCl6 octahedra that share corners with six equivalent Al(1)Cl6 octahedra. The corner-sharing octahedra are not tilted. Rb(1) is bonded in a 12-coordinate geometry to twelve equivalent Cl(1) atoms. Al(1) is bonded to six equivalent Cl(1) atoms to form AlCl6 octahedra that share corners with six equivalent Cs(1)Cl6 octahedra. The corner-sharing octahedra are not tilted. Cl(1) is bonded in a distorted linear geometry to one Cs(1), four equivalent Rb(1), and one Al(1) atom.
