Abstract: In the title compound, C26H16N4O3S, the thiadiazole ring adopts an envelope conformation, with the S atom occupying the flap position. The dihedral angle between the two quinoline ring systems is 55.32 (8)°. In the crystal, the molecules are linked into chains along  by C-HO hydrogen bonds. The chains are connected via - interactions involving one of the pyridine rings [centroid-centroid distance = 3.5558 (18) Å].
