In the title compound, C14H11N50S2, the triazolo-thiadiazole system is essentially planar (r.m.s. deviation = 0.002 A) and makes dihedral angles of 6.33 (12) and 42.95 (14) with the planes of the oxazole and phenyl rings, respectively. In the crystal, face-to-face pi-pi interactions are observed between the thiadiazole and oxazole rings [centroid-centroid distance = 3.4707 (18) angstrom], leading to columns along [010].
