Cs2CuGaCl6 is (Cubic) Perovskite-derived structured and 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 Cu(1)Cl6 octahedra, and faces with four equivalent Ga(1)Cl6 octahedra. Cu(1) is bonded to six equivalent Cl(1) atoms to form CuCl6 octahedra that share corners with six equivalent Ga(1)Cl6 octahedra and faces with eight equivalent Cs(1)Cl12 cuboctahedra. The corner-sharing octahedra are not tilted. Ga(1) is bonded to six equivalent Cl(1) atoms to form GaCl6 octahedra that share corners with six equivalent Cu(1)Cl6 octahedra and faces with eight equivalent Cs(1)Cl12 cuboctahedra. The corner-sharing octahedra are not tilted. Cl(1) is bonded to four equivalent Cs(1), one Cu(1), and one Ga(1) atom to form a mixture of distorted edge, face, and corner-sharing ClCs4GaCu octahedra. The corner-sharing octahedral tilt angles range from 0-60°.
