Rb2KScBr6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. Rb(1) is bonded to twelve equivalent Br(1) atoms to form RbBr12 cuboctahedra that share corners with twelve equivalent Rb(1)Br12 cuboctahedra, faces with six equivalent Rb(1)Br12 cuboctahedra, faces with four equivalent K(1)Br6 octahedra, and faces with four equivalent Sc(1)Br6 octahedra. K(1) is bonded to six equivalent Br(1) atoms to form KBr6 octahedra that share corners with six equivalent Sc(1)Br6 octahedra and faces with eight equivalent Rb(1)Br12 cuboctahedra. The corner-sharing octahedra are not tilted. Sc(1) is bonded to six equivalent Br(1) atoms to form ScBr6 octahedra that share corners with six equivalent K(1)Br6 octahedra and faces with eight equivalent Rb(1)Br12 cuboctahedra. The corner-sharing octahedra are not tilted. Br(1) is bonded in a linear geometry to four equivalent Rb(1), one K(1), and one Sc(1) atom.
