Rb2LiPrI6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. Rb(1) is bonded to twelve equivalent I(1) atoms to form RbI12 cuboctahedra that share corners with twelve equivalent Rb(1)I12 cuboctahedra, faces with six equivalent Rb(1)I12 cuboctahedra, faces with four equivalent Li(1)I6 octahedra, and faces with four equivalent Pr(1)I6 octahedra. Li(1) is bonded to six equivalent I(1) atoms to form LiI6 octahedra that share corners with six equivalent Pr(1)I6 octahedra and faces with eight equivalent Rb(1)I12 cuboctahedra. The corner-sharing octahedra are not tilted. Pr(1) is bonded to six equivalent I(1) atoms to form PrI6 octahedra that share corners with six equivalent Li(1)I6 octahedra and faces with eight equivalent Rb(1)I12 cuboctahedra. The corner-sharing octahedra are not tilted. I(1) is bonded in a linear geometry to four equivalent Rb(1), one Li(1), and one Pr(1) atom.
