(Rb2SCl6)2F2 crystallizes in the cubic Fm-3m space group. The structure consists of four hydrofluoric acid atoms inside a Rb2SCl6 framework. In the Rb2SCl6 framework, Rb(1) is bonded to twelve equivalent Cl(1) atoms to form RbCl12 cuboctahedra that share corners with twelve equivalent Rb(1)Cl12 cuboctahedra, faces with six equivalent Rb(1)Cl12 cuboctahedra, and faces with four equivalent S(1)Cl6 octahedra. S(1) is bonded to six equivalent Cl(1) atoms to form SCl6 octahedra that share faces with eight equivalent Rb(1)Cl12 cuboctahedra. Cl(1) is bonded to four equivalent Rb(1) and one S(1) atom to form a mixture of distorted corner, face, and edge-sharing ClRb4S square pyramids.
