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 hy-droxy 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 mol-ecular 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, intra-molecular hypervalent S⋯O inter-actions persist in each anion [3.078 (2) and 2.8730 (19) Å]. In the crystal, supra-molecular 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 inter-actions.
