CsRbMnF6 crystallizes in the cubic F-43m space group. Cs(1) is bonded to twelve equivalent F(1) atoms to form CsF12 cuboctahedra that share corners with twelve equivalent Cs(1)F12 cuboctahedra, faces with six equivalent Rb(1)F12 cuboctahedra, and faces with four equivalent Mn(1)F6 octahedra. 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 Cs(1)F12 cuboctahedra, and faces with four equivalent Mn(1)F6 octahedra. Mn(1) is bonded to six equivalent F(1) atoms to form MnF6 octahedra that share faces with four equivalent Cs(1)F12 cuboctahedra and faces with four equivalent Rb(1)F12 cuboctahedra. F(1) is bonded in a single-bond geometry to two equivalent Cs(1), two equivalent Rb(1), and one Mn(1) atom.
