The molecule of the title compound, C13H9Cl2N5OS2, is essentially non-planar, with a dihedral angle of 68.6 (2)degrees between the thiadiazole and triazole rings, and a dihedral angle of 62.8 (1)degrees between the thiadiazole and benzene rings. The crystal packing is stabilized by intermolecular C-H center dot center dot center dot N hydrogen bonds, which link dimers into zigzag chains along the b axis.
