The first title compound, C10H7FN2OS, crystallizes in space group P1 with two independent molecules in the asymmetric unit, which form a dimer with an R22(8) motif through pairwise N—H⋯N hydrogen bonds. In the crystal of (I), N—H⋯O hydrogen bonds bind the dimers into zigzag ribbons running along the [100] direction, generating R44(14) motifs. The second title compound, C10H7ClN2OS (space group I2/a), contains one molecule in the asymmetric unit, which forms a dimer with an R22(8) motif via inversion symmetry. In the extended structure, the molecules form zigzag ribbons in the [100] direction by N—H⋯N and N—H⋯O hydrogen bonds, resulting in consecutive R41(8)R21(5)R22(8)R21(5)R41(8) motifs. The Hirshfeld surface analyses of the compounds (I) and (II) indicates that the most important factors influencing the crystal packing are H⋯H interactions [21.1% for molecule A of (I), 20.3% for molecule B of (I) and 21.0% for (II)].
