RbBiF6 crystallizes in the trigonal R-3 space group. Rb(1) is bonded to twelve equivalent F(1) atoms to form RbF12 cuboctahedra that share corners with six equivalent Bi(1)F6 octahedra, edges with six equivalent Rb(1)F12 cuboctahedra, and faces with two equivalent Bi(1)F6 octahedra. The corner-sharing octahedral tilt angles are 44°. Bi(1) is bonded to six equivalent F(1) atoms to form BiF6 octahedra that share corners with six equivalent Rb(1)F12 cuboctahedra and faces with two equivalent Rb(1)F12 cuboctahedra. F(1) is bonded in a distorted single-bond geometry to two equivalent Rb(1) and one Bi(1) atom.

The corner-sharing octahedral tilt angles are 44°. There are six shorter (2.94 Å) and six longer (3.12 Å) Rb(1)-F(1) bond lengths. Bi(1) is bonded to six equivalent F(1) atoms to form BiF6 octahedra that share corners with six equivalent Rb(1)F12 cuboctahedra and faces with two equivalent Rb(1)F12 cuboctahedra. All Bi(1)-F(1) bond lengths are 2.02 Å. F(1) is bonded in a distorted single-bond geometry to two equivalent Rb(1) and one Bi(1) atom.
