The title compound, C23H22FN5S, exists in a trans conformation with respect to the methene C=C and the acyclic N=C bonds. The 1,2,4-triazole-5(4H)-thione ring makes dihedral angles of 88.66 (9) and 84.51 (10)°, respectively, with the indole and benzene rings. In the crystal, mol-ecules are linked by pairs of N-H⋯S hydrogen bonds, forming inversion dimers with an R 2 (2)(8) ring motif. The dimers are linked via C-H⋯π inter-actions, forming chains along [1-10]. The chains are linked via π-π inter-actions involving inversion-related triazole rings [centroid-centroid distance = 3.4340 (13) Å], forming layers parallel to the ab plane.
The title indolin-2-one compound, C28H23FN4O·C2H6O, crystallizes as a 1:1 ethanol solvate. The ethanol mol-ecule is disordered over two positions with refined site occupancies of 0.560 (14) and 0.440 (14). The pyrazole ring makes dihedral angles of 84.16 (10) and 85.33 (9)° with the indolin-2-one and indole rings, respectively, whereas the dihedral angle between indolin-2-one and indole rings is 57.30 (7)°. In the crystal, the components are linked by N-H⋯O and O-H⋯O hydrogen bonds, forming an inversion mol-ecule-solvate 2:2 dimer with R 4 (4)(12) ring motifs. The crystal structure is consolidated by π-π inter-action between pairs of inversion-related indolin-2-one rings [inter-planar spacing = 3.599 (2) Å].
The asymmetric unit of the titled compound, C22H20FN5S, comprises two independent mol-ecules (A and B), both of which have a trans conformation with respect to the methene C=C [1.342 (2) and 1.335 (2) Å] and the acyclic N=C [1.283 (2) and 1.281 (2) Å] bonds. In mol-ecule A, the triazole ring makes dihedral angles of 55.01 (12) and 18.17 (9)° with the benzene and indole rings, respectively. The corresponding dihedral angles for mol-ecule B are 54.54 (11) and 14.60 (10)°, respectively. In the crystal, mol-ecules are consolidated into -A-B-A-B- chains along [010] via N-H⋯N hydrogen bonds. The chains are further linked into layers parallel to the ac plane via π-π inter-actions involving inversion-related triazole rings [centroid-centroid distances = 3.3436 (11)-3.4792 (13) Å].
