Rb3InCl6 is (Cubic) Perovskite-like structured and crystallizes in the cubic Fm-3m space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded to twelve equivalent Cl(1) atoms to form distorted RbCl12 cuboctahedra that share corners with twelve equivalent Rb(1)Cl12 cuboctahedra, faces with six equivalent Rb(1)Cl12 cuboctahedra, faces with four equivalent Rb(2)Cl6 octahedra, and faces with four equivalent In(1)Cl6 octahedra. In the second Rb site, Rb(2) is bonded to six equivalent Cl(1) atoms to form RbCl6 octahedra that share corners with six equivalent In(1)Cl6 octahedra and faces with eight equivalent Rb(1)Cl12 cuboctahedra. The corner-sharing octahedra are not tilted. In(1) is bonded to six equivalent Cl(1) atoms to form InCl6 octahedra that share corners with six equivalent Rb(2)Cl6 octahedra and faces with eight equivalent Rb(1)Cl12 cuboctahedra. The corner-sharing octahedra are not tilted. Cl(1) is bonded in a linear geometry to one Rb(2), four equivalent Rb(1), and one In(1) atom.
