Rb2RhF6 crystallizes in the trigonal P-3m1 space group. Rb(1) is bonded to twelve equivalent F(1) atoms to form distorted RbF12 cuboctahedra that share corners with six equivalent Rb(1)F12 cuboctahedra, corners with three equivalent Rh(1)F6 octahedra, faces with eight equivalent Rb(1)F12 cuboctahedra, and faces with three equivalent Rh(1)F6 octahedra. The corner-sharing octahedral tilt angles are 18°. Rh(1) is bonded to six equivalent F(1) atoms to form RhF6 octahedra that share corners with six equivalent Rb(1)F12 cuboctahedra and faces with six equivalent Rb(1)F12 cuboctahedra. F(1) is bonded in a distorted single-bond geometry to four equivalent Rb(1) and one Rh(1) atom.
