The structure described by Rb2PrCuCl6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. Rb(1) is bonded to twelve equivalent Cl(1) atoms to form RbCl12 cuboctahedra that share corners with twelve equivalent Rb(1)Cl12 cuboctahedra, faces with six equivalent Rb(1)Cl12 cuboctahedra, faces with four equivalent Pr(1)Cl6 octahedra, and faces with four equivalent Cu(1)Cl6 octahedra. Pr(1) is bonded to six equivalent Cl(1) atoms to form PrCl6 octahedra that share corners with six equivalent Cu(1)Cl6 octahedra and faces with eight equivalent Rb(1)Cl12 cuboctahedra. The corner-sharing octahedra are not tilted. Cu(1) is bonded to six equivalent Cl(1) atoms to form CuCl6 octahedra that share corners with six equivalent Pr(1)Cl6 octahedra and faces with eight equivalent Rb(1)Cl12 cuboctahedra. The corner-sharing octahedra are not tilted. Cl(1) is bonded in a distorted linear geometry to four equivalent Rb(1), one Pr(1), and one Cu(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
