چکیده
In the title acrylonitrile derivative, C(17)H(14)N(2)OS, the central amino-acryl-aldehyde O=C-C=C-NH unit, wherein an intra-molecular N-H⋯O hydrogen bond generates an S(6) ring motif, is approximately planar, with an r.m.s. deviation of 0.0234 (2) Å for the five non-H atoms. This plane makes dihedral angles of 41.04 (9) and 84.86 (10)° with the two phenyl rings. The dihedral angle between the two phenyl rings is 54.82 (10)°. An intra-molecular C-H⋯N hydrogen bond is also present. In the crystal, weak C-H⋯π and π-π inter-actions, with a centroid-centroid distance of 3.8526 (14) Å, are observed.

The title compound, C(15)H(12)N(2)OS(2), is an example of a push-pull butadiene in which the electron-releasing methyl-sulfanyl groups and electron-withdrawing nitrile groups on either end of the butadiene chain enhance the conjugation in the system. Short intra-molecular C-H⋯S inter-actions are observed. In the crystal structure, an O⋯C short contact of 2.917 (3) Å is observed.
