Cs2KInBr6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. Cs(1) is bonded to twelve equivalent Br(1) atoms to form CsBr12 cuboctahedra that share corners with twelve equivalent Cs(1)Br12 cuboctahedra, faces with six equivalent Cs(1)Br12 cuboctahedra, faces with four equivalent K(1)Br6 octahedra, and faces with four equivalent In(1)Br6 octahedra. K(1) is bonded to six equivalent Br(1) atoms to form KBr6 octahedra that share corners with six equivalent In(1)Br6 octahedra and faces with eight equivalent Cs(1)Br12 cuboctahedra. The corner-sharing octahedra are not tilted. In(1) is bonded to six equivalent Br(1) atoms to form InBr6 octahedra that share corners with six equivalent K(1)Br6 octahedra and faces with eight equivalent Cs(1)Br12 cuboctahedra. The corner-sharing octahedra are not tilted. Br(1) is bonded in a distorted linear geometry to four equivalent Cs(1), one K(1), and one In(1) atom.
