In the title compound, C24H26FN3O, the cyclo­hexane ring adopts a chair conformation; the propyl substituent is in an equatorial orientation and the bond-angle sum at the C atom bonded to the carbohydrazide N atom is 360.0°. The dihedral angle between the 1H-indole ring system and the phenyl ring is 82.77 (13)°. A weak intra­molecular C—H...π contact occurs. In the crystal, pairs of mol­ecules related by a crystallographic twofold axis are linked by bifurcated N—H...(O,N) hydrogen bonds; a C—H...O inter­action occurs between the same pair. The dimers are linked by C—H...F and C—H...π inter­actions, generating a three-dimensional network.

The title compound, C22H22FN3O, crystallized with two independent mol­ecules (A and B) in the asymmetric unit; these are linked by a pair of N—H...O hydrogen bonds, forming a pseudo-centrosymmetric dimer with an R22(10) motif. In addition, a number of C—H...π inter­actions are also observed. The 1H-indole ring systems in mol­ecules A and B are essentially planar [maximum deviations of 0.019 (2) and 0.014 (2) Å, respectively] and make dihedral angles of 77.64 (10) and 69.50 (9)°, respectively, with thephenyl rings.

In the title compound, C24H24FN3O2S, the 1,3-thia­zolidine ring adopts an envelope conformation with the S atom as the flap, while the cyclo­hexane ring is in a chair conformation. In the crystal, mol­ecules are linked by N—H...O and C—H...F hydrogen bonds, forming a three-dimensional network. The unit cell contains six voids of 57 Å3, but the residual electron density (highest peak = 0.23 e Å−3 and deepest hole = −0.19 e Å−3) in the difference Fourier map suggests no solvent mol­ecule occupies this void.

In the title compound, C14H17NO3, the nine-membered 1H-indole ring system is essentially planar [maximum deviation = 0.019 (1) Å]. In the crystal, mol­ecules are linked via N—H...O hydrogen bonds, forming chains along [001]. These chains are linked via C—H...O hydrogen bonds and C—H...π inter­actions, forming a two-dimensional network lying parallel to the ac plane.

In the title compound, C26H25ClN2, the phenyl rings and the 2-(4-chloro­phen­yl) group make dihedral angles of 30.03 (11), 67.49 (12) and 41.56 (11)°, respectively, with the imidazole ring. In the crystal, the mol­ecules inter­act with each other via very weak C—H...π contacts, forming layers parallel to (110).

In the title compound, C14H13N3O2S, the dihedral angle between the thio­phene and phenyl rings is 24.95 (8)°. The mol­ecular structure is consolidated by intra­molecular N—H...O and C—H...S inter­actions. The crystal structure features N—H...N and N—H...O hydrogen bonds forming centrosymmetric R22(12) dimers, which are linked into a two-dimensional network parallel to (011) with an S(6)R22S(6) motif. In addition, π–π stacking inter­actions [centroid–centroid distance = 3.7013 (12) Å] occur between the thio­phene and phenyl rings of adjacent mol­ecules.

In the title compound, C13H15N3S, the 4,5-di­hydro-3H-1,2,4-triazole ring is nearly planar [maximum deviation = 0.020 (1) Å], while the cyclo­hexane ring adopts a chair conformation. The dihedral angle between the 4,5-di­hydro-3H-1,2,4-triazole ring and the phenyl ring is 74.68 (7)°. No specific inter­molecular inter­actions are discerned in the crystal packing.

In the title compound, C16H14O4, the benzene rings are inclined at a dihedral angle of 75.14 (9)°. The torsion angle of the bridging O—C—C—O group is −76.50 (11)°. In the crystal, mol­ecules are linked by C—H...O hydrogen bonds, forming C(6) chains along [100]. Furthermore, C—H...π inter­actions and π–π stacking inter­actions [centroid–centroid distances = 3.6957 (7) and 3.6735 (8) Å] contribute to the stability of the crystal packing.

In the title compound, C12H7N3OS, the five-membered 1,3-thia­zolidine ring is nearly planar [maximum deviation = 0.032 (2) Å] and makes a dihedral angle of 84.14 (9)° with the phenyl ring.
