Benzyl 3-[(E)-1-(pyrazin-2-yl)ethyl­idene]dithio­carbazate

The title compound, C(14)H(14)N(4)S(2), was obtained from a condensation reaction of benzyl dithio­carbazate and acetyl­pyrazine. The asymmetric unit contains two independent mol­ecules, in each of which the pyrazine ring and dithio­carbazate unit are approximately co-planar, the r.m.s. deviations being 0.0304 and 0.0418 Å. The mean plane is oriented with respect to the benzene ring at 49.22 (4)° in one mol­ecule and at 69.76 (7)° in the other. In the crystal, the mol­ecules are linked to each other via inter­molecular N—H⋯S hydrogen bonds, forming centrosymmetric supra­molecular dimers.
