Experimental

R factor = 0.024; wR factor = 0.066; data-to-parameter ratio = 21.0. In the title compound, C7H5ClFN3S, the 1,3-benzothiazole ring system is nearly planar (r.m.s. deviation = 0.023 Å). In the crystal, molecules are linked via intermolecular N—H N hydrogen bonds into a two-dimensional network parallel to (100).
