Rb2LiTiF6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. Rb(1) is bonded to twelve equivalent F(1) atoms to form RbF12 cuboctahedra that share corners with twelve equivalent Rb(1)F12 cuboctahedra, faces with six equivalent Rb(1)F12 cuboctahedra, faces with four equivalent Li(1)F6 octahedra, and faces with four equivalent Ti(1)F6 octahedra. Li(1) is bonded to six equivalent F(1) atoms to form LiF6 octahedra that share corners with six equivalent Ti(1)F6 octahedra and faces with eight equivalent Rb(1)F12 cuboctahedra. The corner-sharing octahedra are not tilted. Ti(1) is bonded to six equivalent F(1) atoms to form TiF6 octahedra that share corners with six equivalent Li(1)F6 octahedra and faces with eight equivalent Rb(1)F12 cuboctahedra. The corner-sharing octahedra are not tilted. F(1) is bonded in a distorted linear geometry to four equivalent Rb(1), one Li(1), and one Ti(1) atom.
