Abstract: The title compound, [C₇H₁₀N₃S₂]⁺·Cl^-, exists as an ionic compound of a dithiocarbazate system, with a zwitterionic ⁺H₃NNCS^- moiety and a protonated pyridine ring. The C-S thione bond distance of the zwitterionic moiety [1.708  (2)  Å] is longer than the normal double bond and the C-N of the carbazate moiety has double-bond character. The crystal packing is stabilized by intramolecular hydrogen bonds, which form a two-dimensional network perpendicular to b.
