In the crystal structure of the title compound, C5H3Cl3N4S, two molecules related by a centre of symmetry demonstrate extremely short intermolecular SN contacts of 2.783 (2) Å. The crystal packing also exhibits - interactions indicated by a short distance of 3.340 (1) Å between the centroids of the triazole rings of neighbouring molecules.
