Crystal structure of 2-{[2-(3-phenyl­allyl­idene)hydrazin-1-yl]thio­carbonyl­sulfanylmeth­yl}pyridinium chloride

In the title salt of an S-substituted di­thio­carbazate, C₁₆H₁₆N₃S₂⁺·Cl⁻, the dihedral angles between the almost planar (r.m.s deviation = 0.005 Å) central CN₂S₂ 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.
