The asymmetric unit of the title compound, C16H12ClN3S, contains two independent molecules whose conformations differ primarily in the orientations of the phenyl and chlorobenzene rings with respect to the thiazole ring. In the first molecule, the dihedral angles are 3.0 (1) and 9.2 (1)degrees, respectively, for the phenyl ring and the chlorobenzene ring, while in the second molecule, the corresponding angles are 18.6 (1) and 23.4 (1)degrees. In the crystal, the two independent molecules are associated via complementary N-H center dot center dot center dot N hydrogen bonds into a dimer. These dimers are associated through weak C-H center dot center dot center dot Cl and C-H center dot center dot center dot S interactions into supramolecular chains propagating along the alpha-axis direction.
