The title compound, C23H22FN5S, exists in atransconformation 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, molecules are linked by pairs of N—H...S hydrogen bonds, forming inversion dimers with anR22(8) ring motif. The dimers are linkedviaC—H...π interactions, forming chains along [1-10]. The chains are linkedviaπ—π interactions involving inversion-related triazole rings [centroid–centroid distance = 3.4340 (13) Å], forming layers parallel to theabplane.
