RbAsF6 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 As(1)F6 octahedra, edges with six equivalent Rb(1)F12 cuboctahedra, and faces with two equivalent As(1)F6 octahedra. The corner-sharing octahedral tilt angles are 36°. As(1) is bonded to six equivalent F(1) atoms to form AsF6 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 As(1) atom.

The corner-sharing octahedral tilt angles are 36°. There are six shorter (2.94 Å) and six longer (3.05 Å) Rb(1)-F(1) bond lengths. As(1) is bonded to six equivalent F(1) atoms to form AsF6 octahedra that share corners with six equivalent Rb(1)F12 cuboctahedra and faces with two equivalent Rb(1)F12 cuboctahedra. All As(1)-F(1) bond lengths are 1.75 Å. F(1) is bonded in a distorted single-bond geometry to two equivalent Rb(1) and one As(1) atom.
