Cs2InAlCl6 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 In(1)Cl6 octahedra, and faces with four equivalent Al(1)Cl6 octahedra. In(1) is bonded to six equivalent Cl(1) atoms to form InCl6 octahedra that share corners with six equivalent Al(1)Cl6 octahedra and faces with eight equivalent Cs(1)Cl12 cuboctahedra. The corner-sharing octahedra are not tilted. Al(1) is bonded to six equivalent Cl(1) atoms to form AlCl6 octahedra that share corners with six equivalent In(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 distorted single-bond geometry to four equivalent Cs(1), one In(1), and one Al(1) atom.
