Synthesis and Characterization of Heterocyclic Compounds

In the title compound, C(14)H(13)N(3)OS(2), the thio-phene ring is disordered over two orientations by ca 180° about the C-C bond axis linking the ring to the rest of the mol-ecule, with a site-occupancy ratio of 0.651 (5):0.349 (5). The central 1,3,4-oxadiazole-2(3H)-thione ring forms dihedral angles of 9.2 (5), 4.6 (11) and 47.70 (7)° with the major and minor parts of the disordered thio-phene ring and the terminal phenyl ring, respectively. In the crystal, no significant inter-molecular hydrogen bonds are observed. The crystal packing is stabilized by π-π inter-actions [centroid-centroid distance = 3.589 (2) Å].
