title: Benzyl 3-[(E)-1-(pyrazin-2-yl)ethyl-idene]dithio-carbazate.
abstract: The title compound, C(14)H(14)N(4)S(2), was obtained from a condensation reaction of benzyl dithio-carbazate and acetyl-pyrazine. The asymmetric unit contains two independent mol-ecules, in each of which the pyrazine ring and dithio-carbazate 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 mol-ecule and at 69.76 (7)° in the other. In the crystal, the mol-ecules are linked to each other via inter-molecular N-H⋯S hydrogen bonds, forming centrosymmetric supra-molecular dimers.
