In the crystal of the title compound, C9H9ClFN3S, the molecules are interconnected by N—H⋯S and N—H⋯F hydrogen bonds. There are two different N—H⋯S hydrogen bond: the stronger one links molecules into infinite chains along the b axis with graph-set motif C(4), while the weaker N—H⋯S hydrogen bond combines with the previous one into an R 2 2(8) network. Moreover, the chains are linked into layers parallel to (102) by weak N—H⋯F hydrogen bonds, which form an R 2 2(22) ring motif. In addition, there are also weak π–π interactions between the benzene rings of adjacent molecules [centroid–centroid distance = 3.8997 (15) Å]
