tert-But­yl(2-hy­droxy­eth­yl)aza­nium 4-[(1,3-thia­zol-2-yl­aza­nid­yl)sulfon­yl]aniline

Two pairs of independent cations and anions comprise the asymmetric unit of the title salt, C(6)H(16)NO(+)·C(9)H(8)N(3)O(2)S(2) (−). The cations are virtually superimposable and each exhibits a gauche disposition of the hy­droxy O and ammonium N atoms [the O—C—C—N torsion angles are 55.5 (3) and 57.5 (3)°]. Significant differences are seen in the mol­ecular structures of the anions as seen in the S—N—C—S [1.1 (3) and 32.9 (3)°] and C—S—N—C [−69.7 (2) and 91.4 (2)°] torsion angles. Despite the variations in conformation, intra­molecular hypervalent S⋯O inter­actions persist in each anion [3.078 (2) and 2.8730 (19) Å]. In the crystal, supra­molecular double layers are formed in the bc plane, being sustained by O—H⋯N, N—H⋯O and N—H⋯N hydrogen bonding. These are connected along the a axis via C—H⋯O inter­actions.
