Rb2MnTlF6 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 Mn(1)F6 octahedra, and faces with four equivalent Tl(1)F6 octahedra. Mn(1) is bonded to six equivalent F(1) atoms to form MnF6 octahedra that share corners with six equivalent Tl(1)F6 octahedra and faces with eight equivalent Rb(1)F12 cuboctahedra. The corner-sharing octahedra are not tilted. Tl(1) is bonded to six equivalent F(1) atoms to form TlF6 octahedra that share corners with six equivalent Mn(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 1-coordinate geometry to four equivalent Rb(1), one Mn(1), and one Tl(1) atom.
