K2InAlBr6 crystallizes in the cubic Fm-3m space group. K(1) is bonded to twelve equivalent Br(1) atoms to form distorted KBr12 cuboctahedra that share corners with twelve equivalent K(1)Br12 cuboctahedra, faces with six equivalent K(1)Br12 cuboctahedra, faces with four equivalent In(1)Br6 octahedra, and faces with four equivalent Al(1)Br6 octahedra. In(1) is bonded to six equivalent Br(1) atoms to form InBr6 octahedra that share corners with six equivalent Al(1)Br6 octahedra and faces with eight equivalent K(1)Br12 cuboctahedra. The corner-sharing octahedra are not tilted. Al(1) is bonded to six equivalent Br(1) atoms to form AlBr6 octahedra that share corners with six equivalent In(1)Br6 octahedra and faces with eight equivalent K(1)Br12 cuboctahedra. The corner-sharing octahedra are not tilted. Br(1) is bonded in a distorted linear geometry to four equivalent K(1), one In(1), and one Al(1) atom.
