N'-[Bis(benzyl-sulfan-yl)methyl-idene]benzohydrazide.

In the title hydrazonodithio-ate, C(21)H(19)N(3)OS(2), the amide group is twisted out of the plane through the S(2)C=N atoms: the C-N-N-C torsion angle is 139.71†(13)°. The pyridine ring forms dihedral angles of 52.96†(8) and 86.46†(8)° with the phenyl rings, and the latter are approximately orthogonal [dihedral angle = 76.42†(9)°]. Supra-molecular chains sustained by N-H⋯O hydrogen bonds and propagated by glide symmetry along the c axis are found in the crystal structure. The chains are consolidated into a three-dimensional architecture by C-H⋯O and C-H⋯N inter-actions.
