NaBS2 crystallizes in the trigonal R-3c space group. Na(1) is bonded in a 6-coordinate geometry to two equivalent S(1) and four equivalent S(2) atoms. B(1) is bonded in a trigonal planar geometry to one S(2) and two equivalent S(1) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded in a 4-coordinate geometry to two equivalent Na(1) and two equivalent B(1) atoms. In the second S site, S(2) is bonded in a 5-coordinate geometry to four equivalent Na(1) and one B(1) atom.
NaBS2 crystallizes in the trigonal R-3c space group. 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 3.03 Å. There are two shorter (2.92 Å) and two longer (3.05 Å) Na(1)-S(2) bond lengths. B(1) is bonded in a trigonal planar geometry to one S(2) and two equivalent S(1) atoms. The B(1)-S(2) bond length is 1.77 Å. Both B(1)-S(1) bond lengths are 1.82 Å. There are two inequivalent S sites. In the first S site, S(1) is bonded in a 4-coordinate geometry to two equivalent Na(1) and two equivalent B(1) atoms. In the second S site, S(2) is bonded in a 5-coordinate geometry to four equivalent Na(1) and one B(1) atom.
