The title compound, C5H3N3OS, is almost planar (r.m.s. deviation for the ten non-H atoms = 0.018 Å) and forms an extended layer structure in the (100) plane, held together via hydrogen-bonding interactions between adjacent molecules. Of particular note is the occurrence of RC - H⋯N - =N + =NR interactions between an aromatic C - H group and an azide moiety which, in conjunction with a complementary C - H⋯O=C interaction, forms a nine-membered ring.
