In the title compound, C17H18N4OS2, the 2-thienyl ring is disordered over two co-planar, opposite orientations in a 0.684 (2): 0.316 ratio. The 1,3,4-oxa-diazole ring is almost co-planar with the attached 2-thienyl ring [dihedral angles of 5.34 (19) and 4.8 (5)° for the major and minor components, respectively]. The relative disposition of the thione- and ring-S atoms is anti for the major orientation of the 2-thienyl residue. Overall, the shape of the mol-ecule approximates the letter V. In the crystal, a three-dimensional architecture is consolidated by a combination of weak C-H⋯S and C-H⋯π contacts.
