The complete molecule of the title compound, C20H18N4O2S2, is generated by crystallographic inversion symmetry. The benzene ring is almost coplanar with the oxadiazole ring [dihedral angle = 7.2 (2)°].
Functionalized 1,3,4-oxadiazole derivatives are of interest because of their biological activity and their wide applications in medicine, coordination chemistry and their use as organic electroluminescent (EL) devices, since these compounds possess good electron-accepting properties, see: Bentiss et al. (2000); Hughes & Bryce (2005); Navidpour et al. (2006).
