Na6(SO4)2FCl crystallizes in the cubic Fm-3m space group. Na(1) is bonded in a 6-coordinate geometry to four equivalent O(1), one Cl(1), and one F(1) atom. S(1) is bonded in a tetrahedral geometry to four equivalent O(1) atoms. O(1) is bonded in a 4-coordinate geometry to three equivalent Na(1) and one S(1) atom. Cl(1) is bonded to six equivalent Na(1) atoms to form ClNa6 octahedra that share corners with six equivalent F(1)Na6 octahedra. The corner-sharing octahedra are not tilted. F(1) is bonded to six equivalent Na(1) atoms to form FNa6 octahedra that share corners with six equivalent Cl(1)Na6 octahedra. The corner-sharing octahedra are not tilted.
