5-(2-Methylphenyl)-1,3,4-thiadiazol-2-amine

Y. Wang, X.-J. Kong, R. Wan, F. Han and P. Wang

Abstract: The asymmetric unit of the title compound, C₉H₉N₃S, contains two crystallographically independent molecules, in which the thiadiazole and tolyl rings are oriented at dihedral angles of 32.25 (3) and 74.50 (3)°. An intramolecular C-HS interaction results in the formation of a five-membered ring. In the crystal structure, intermolecular N-HN hydrogen bonds link the molecules into chains along the a axis. A - contact between the thiadiazole rings [centroid-centroid distance = 3.910 (3) Å] may further stabilize the structure. There is also a weak C-H interaction.
