Abstract: In the title compound, C₁₆H₁₃N₅O₂S, the five non-H atoms of the urea linkage adopt a planar configuration owing to the presence of an intramolecular N-HO hydrogen bond. The maximum deviation from planarity is 0.022 (2) Å. The thiadiazole and pyridine heterocyclic rings are close to being coplanar, with a dihedral angle of 6.7 (2)° between their mean planes. Intermolecular N-HO hydrogen bonds link two neighbouring molecules into centrosymmetric R₂²(8) dimers. Four C atoms and the attached H atoms of the benzene ring are disordered over two positions of equal occupancy.
