Abstract: Two pairs of independent cations and anions comprise the asymmetric unit of the title salt, C6H16NO+·C9H8N3O2S2-. 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-HN, N-HO and N-HN hydrogen bonding. These are connected along the a axis via C-HO interactions.
