NaAlS2O17O2 crystallizes in the monoclinic C2/c space group. The structure consists of four 7782-44-7 molecules inside a NaAlS2O17 framework. In the NaAlS2O17 framework, Na(1) is bonded to two equivalent O(2), two equivalent O(8), and two equivalent O(9) atoms to form NaO6 octahedra that share corners with two equivalent Na(1)O6 octahedra and corners with two equivalent S(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 63°. Al(1) is bonded in a square co-planar geometry to two equivalent O(5), two equivalent O(6), and two equivalent O(7) atoms. S(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form SO4 tetrahedra that share  a cornercorner with one Na(1)O6 octahedra. The corner-sharing octahedral tilt angles are 51°. There are nine inequivalent O sites. In the first O site, O(5) is bonded in a single-bond geometry to one Al(1) atom. In the second O site, O(6) is bonded in a distorted bent 120 degrees geometry to one Al(1) and one O(9) atom. In the third O site, O(7) is bonded in a single-bond geometry to one Al(1) atom. In the fourth O site, O(8) is bonded in a bent 120 degrees geometry to two equivalent Na(1) atoms. In the fifth O site, O(9) is bonded in a bent 120 degrees geometry to one Na(1) and one O(6) atom. In the sixth O site, O(1) is bonded in a single-bond geometry to one S(1) atom. In the seventh O site, O(2) is bonded in a bent 120 degrees geometry to one Na(1) and one S(1) atom. In the eighth O site, O(3) is bonded in a single-bond geometry to one S(1) atom. In the ninth O site, O(4) is bonded in a single-bond geometry to one S(1) atom.
