Rb2SnF6 crystallizes in the cubic Fm-3m space group. Rb(1) is bonded to twelve equivalent F(1) atoms to form RbF12 cuboctahedra that share corners with twelve equivalent Rb(1)F12 cuboctahedra, faces with six equivalent Rb(1)F12 cuboctahedra, and faces with four equivalent Sn(1)F6 octahedra. Sn(1) is bonded to six equivalent F(1) atoms to form SnF6 octahedra that share faces with eight equivalent Rb(1)F12 cuboctahedra. F(1) is bonded in a distorted single-bond geometry to four equivalent Rb(1) and one Sn(1) atom.
