Abstract: The title compound, C11H11ClN4OS, crystallizes with two molecules, A and B, in the asymmetric unit in which the dihedral angles between the triazole and benzene rings are 54.6 (3) and 56.0 (3)°. Both molecules feature an intramolecular O-HN hydrogen bond, which generates an S(6) ring. In the crystal, A-B dimers are linked by pairs of weak C-HS hydrogen bonds along with - stacking interactions between the triazole rings [centroid-centroid separations = 3.631 (3) and 3.981 (4)Å]. N-HS hydrogen bonds link the dimers into  chains, which feature R22(8) loops.
