In the title compound, C15H16N2S3 {systematic name: [({[(4-methylphenyl)methyl]sulfanyl}methanethioyl)amino][1-(thiophen-2-yl)ethylidene]amine}, the central CN2S2 residue is almost planar (r.m.s. deviation = 0.0061 Å) and forms dihedral angles of 7.39 (10) and 64.91 (5)° with the thienyl and p-tolyl rings, respectively; the dihedral angle between these rings is 57.52 (6)°. The non-thione S atoms are syn, and with respect to the thione S atom, the benzyl group is anti. In the crystal, centrosymmetrically related molecules self-associate via eight-membered {⋯HNCS}2 synthons. The dimeric aggregates stack along the a axis and are are consolidated into a three-dimensional architecture via methyl-C—H⋯π(benzene) and benzene-C—H⋯π(thienyl) interactions.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
