Crystal structure of 2-cyano-3,3-bis(ethylsulfanyl)-N-o-tolylacrylamide

Abstract

In the molecule of the title compound, C15H18N2OS2, the central S2C=C(CN)C moiety is planar (r.m.s. deviation = 0.029 Å). The C=O and C—CN groups are trans to each other across their common C—C bond. In the crystal, one classical and two `weak' hydrogen bonds combine with borderline N...N and S...S contacts to form layers parallel to (10-2). One ethyl group is disordered over two positions with relative occupancy 0.721/0.279 (7).
