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—HO=C interaction, forms a nine-membered ring.

In the title compound, C9H13NO2S, the dihedral angle between the thiophene ring and the carbamate group is 15.79 (14)°. In the crystal structure, intramolecular C—HO interactions in tandem with the tert-butyl groups render the packing of adjacent molecules in the [001] direction nearly perpendicular [the angle between adjacent thiophene rings is 74.83 (7)°]. An intermolecular N—HO hydrogen bond gives rise to a chain extending along [001]. The crystal studied was found to be a racemic twin.
