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

Abstract

The title compound, C14H14N4S2, 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.
