In the title compound, C20H22N2O2, the central pyridine ring forms a dihedral angle of 76.32 (8)° with the pseudo-axial benzene ring. The cyclooctane ring adopts a twisted boat chair conformation. In the crystal, weak intermolecular C—H
π interactions between inversion-related molecules result in the formation of linear double chains along the b-axis direction.

In the title compound, C19H19FN2O, the cyclooctene ring adopts a twisted boat-chair conformation. The dihedral angle between the plane of the fluorophenyl substituent and that of the pyridine ring is 76.39 (8)°. The F and ortho-H atoms of the fluorobenzene ring are disordered, with occupancy factors of 0.226 (5) and 0.774 (5). In the crystal, no significant interactions are observed between the molecules beyond van der Waals contacts.

In the title compound, C24H14BrN3S, the dihedral angles between the planes of the pyridine ring and the pendant thiophene ring, the indole ring system (r.m.s. deviation = 0.022 Å) and the bromobenzene ring are 9.37 (17), 21.90 (12) and 69.01 (15)°, respectively. The approximate coplanarity of the central ring and the indole ring system is supported by two intramolecular C—HN interactions. In the crystal, inversion dimers linked by pairs of N—HN hydrogen bonds generate R22(16) loops and the dimers are linked by C—Hπ and aromatic π–π stacking [shortest centroid–centroid separation = 3.729 (3) Å] into a three-dimensional network.

In the title compound, C26H16ClN3, the dihedral angles between the central pyridine ring and the pendant phenyl, chlorobenzene and indole rings are 18.52 (12), 48.97 (11) and 21.20 (10)°, respectively. An intramolecular C—HNc (c = cyanide) hydrogen bond occurs. In the crystal, inversion dimers linked by pairs of N—HNc hydrogen bonds generate R22(16) loops.

In the title compound, C27H19N3O, the dihedral angles between the plane of the pyridine ring and those of the indole (r.m.s. deviation = 0.018 Å), phenyl and methoxybenzene substituents are 33.60 (6), 25.28 (7) and 49.31 (7)°, respectively. The N atom of the carbonitrile group is significantly displaced [0.288 (2) Å] from the plane of the pyridine ring, perhaps due to steric crowding. In the crystal, inversion dimers linked by pairs of N—HNn (n = nitrile) hydrogen bonds generate R22(16) loops. Aromatic π–π stacking [centroid–centroid separation = 3.6906 (7) Å] and very weak C—Hπ interactions are also observed".
