NaS is alpha boron-derived structured and crystallizes in the hexagonal P-62m space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 6-coordinate geometry to two equivalent S(1) and four equivalent S(2) atoms. In the second Na site, Na(2) is bonded in a 6-coordinate geometry to two equivalent S(1) and four equivalent S(2) atoms. There are two inequivalent S sites. In the first S site, S(2) is bonded in a 7-coordinate geometry to three equivalent Na(1), three equivalent Na(2), and one S(2) atom. In the second S site, S(1) is bonded in a 7-coordinate geometry to three equivalent Na(1), three equivalent Na(2), and one S(1) atom.

In the first Na site, Na(1) is bonded in a 6-coordinate geometry to two equivalent S(1) and four equivalent S(2) atoms. Both Na(1)-S(1) bond lengths are 2.85 Å. All Na(1)-S(2) bond lengths are 2.82 Å. In the second Na site, Na(2) is bonded in a 6-coordinate geometry to two equivalent S(1) and four equivalent S(2) atoms. Both Na(2)-S(1) bond lengths are 2.91 Å. All Na(2)-S(2) bond lengths are 2.92 Å. There are two inequivalent S sites. In the first S site, S(2) is bonded in a 7-coordinate geometry to three equivalent Na(1), three equivalent Na(2), and one S(2) atom. The S(2)-S(2) bond length is 2.14 Å. In the second S site, S(1) is bonded in a 7-coordinate geometry to three equivalent Na(1), three equivalent Na(2), and one S(1) atom. The S(1)-S(1) bond length is 2.12 Å.
