(Pyridin-4-yl)methyl N′-(3-phenyl­allyl­idene)hydrazinecarbodithio­ate

In the title compound, C₁₆H₁₅N₃S₂, the central C₂N₂S₂ residue is planar (r.m.s. deviation = 0.045 Å) and the pyridyl and benzene rings are inclined and approximately coplanar to this plane, respectively [dihedral angles = 72.85 (9) and 10.73 (9)°], so that, overall, the mol­ecule adopts an L-shape. The conformation about each of the N=C [1.290 (3) Å] and C=C [1.340 (3) Å] bonds is E. Supra­molecular chains along [1-10] are stabilized by N—H...N(pyridine) hydrogen bonding and these are connected into a double layer that stacks along the c-axis direction by C—H...π(pyridine) inter­actions.

2,2-Dibenzyl­hydrazin-1-ium chloride

In the title salt, C₁₄H₁₇N₂⁺·Cl⁻, the central N atom is pyramidal (sum of bond angles = 330.9°) and there is a near orthogonal relationship between the benzene rings [dihedral angle = 89.95 (10)°]. The crystal packing features N—H...Cl hydrogen bonds, which lead to a supra­molecular undulating ribbon along the a axis comprising edge-shared eight-membered {...HNH...Cl}₂ synthons. The chains are connected into layers in the ab plane by C—H...π inter­actions.
