5-(2-Methylphenyl)-1,3,4-thiadiazol-2-amine
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—H...S interaction results in the formation of a five-membered ring. In the crystal structure, intermolecular N—H...N hydrogen bonds link the molecules into chains along the a axis. A π–π contact between the thiadiazole rings [centroid–centroid distance = 3.910 (3) Å] may further stabilize the structure. There is also a weak C—H...π interaction.
