The crystal structure described by RbK2CoF6 crystallizes in the cubic Fm-3m space group. Rb(1) is bonded to six equivalent F(1) atoms to form RbF6 octahedra that share corners with six equivalent Co(1)F6 octahedra and faces with eight equivalent K(1)F12 cuboctahedra. The corner-sharing octahedra are not tilted. K(1) is bonded to twelve equivalent F(1) atoms to form distorted KF12 cuboctahedra that share corners with twelve equivalent K(1)F12 cuboctahedra, faces with six equivalent K(1)F12 cuboctahedra, faces with four equivalent Rb(1)F6 octahedra, and faces with four equivalent Co(1)F6 octahedra. Co(1) is bonded to six equivalent F(1) atoms to form CoF6 octahedra that share corners with six equivalent Rb(1)F6 octahedra and faces with eight equivalent K(1)F12 cuboctahedra. The corner-sharing octahedra are not tilted. F(1) is bonded in a 2-coordinate geometry to one Rb(1), four equivalent K(1), and one Co(1) atom. is represented by the CIF file [CIF]
