RbCoF3 is (Cubic) Perovskite-like structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded to six equivalent F(1) and six equivalent F(2) atoms to form RbF12 cuboctahedra that share corners with six equivalent Rb(1)F12 cuboctahedra, corners with six equivalent Rb(2)F12 cuboctahedra, faces with six equivalent Rb(2)F12 cuboctahedra, faces with two equivalent Co(2)F6 octahedra, and faces with six equivalent Co(1)F6 octahedra. In the second Rb site, Rb(2) is bonded to three equivalent F(1) and nine equivalent F(2) atoms to form RbF12 cuboctahedra that share corners with three equivalent Rb(1)F12 cuboctahedra, corners with six equivalent Rb(2)F12 cuboctahedra, corners with three equivalent Co(1)F6 octahedra, faces with three equivalent Rb(1)F12 cuboctahedra, faces with four equivalent Rb(2)F12 cuboctahedra, faces with three equivalent Co(2)F6 octahedra, and faces with four equivalent Co(1)F6 octahedra.

The corner-sharing octahedral tilt angles are 3°. There are two inequivalent F sites. In the first F site, F(1) is bonded to two equivalent Rb(1), two equivalent Rb(2), and two equivalent Co(1) atoms to form a mixture of distorted corner and face-sharing FRb4Co2 octahedra. The corner-sharing octahedral tilt angles range from 7-60°. In the second F site, F(2) is bonded in a distorted linear geometry to one Rb(1), three equivalent Rb(2), one Co(1), and one Co(2) atom.
