In the title salt of an S -substituted dithiocarbazate, C 16 H 16 N 3 S 2 + ·Cl − , the dihedral angles between the almost planar (r.m.s deviation = 0.005 Å) central CN 2 S 2 residue and the terminal pyridinium and phenyl rings are 80.09 (11) and 3.82 (11)°, respectively, indicating the cation has an L-shape; the amine H and thione S atoms are syn . The conformation about each of the imine [1.376 (3) Å] and ethene [1.333 (4) Å] bonds is E . The shortened C—C bond [1.444 (4) Å] linking the double bonds is consistent with conjugation in this part of the molecule. In the crystal, supramolecular layers with a jagged topology are formed by charged-assisted amine-H...Cl − and pyridinium-N + —H...Cl − hydrogen bonds. The layers stack along the a axis with no specific directional interactions between them.
