In the title salt, C14H20NO+·Cl−, the piperidine ring adopts a chair conformation. In the crystal, the cations and anions are linked by classical N—HCl hydrogen bond and weak C—HCl and C—HO hydrogen bonds; the C—HO hydrogen bonds exhibit R22(14) ring motifs while the C—HCl hydrogen bonds link the molecules into chains along the a-axis direction. π–π stacking is observed between parallel phenyl rings of adjacent cations, the centroid–centroid distance being 3.8164 (15) Å.

In the title compound, C24H20N4, the azepine ring adopts a boat conformation. The dihedral angle between the benzene rings fused to the azepine ring is 49.40 (9)°. The triazole ring makes a dihedral angle of 77.88 (9)° with the terminal phenyl ring. In the crystal, molecules are linked via C—Hπ interactions and a parallel slipped π–π interaction [centroid–centroid distance = 3.7324 (9), normal distance = 3.4060 (6) and slippage = 1.526 Å], forming a three-dimensional network.

In the title compound, C7H8N6O2S, the dihedral angle between the imidazole and thiadiazole rings is 70.86 (15)°. In the crystal, molecules are linked into [10-1] chains by N—HN hydrogen bonds, which incorporate centrosymmetric R22(8) and R22(18) loops. The chains are linked by C—HO and C—HN interactions, generating a three-dimensional network. Very weak π–π stacking [centroid–centroid distance = 3.901 (17) Å] is also observed.

In the title compound, C23H20F3N3O3S2, the benzoimidazole unit makes dihedral angles of 5.02 (1) and 76.42 (1)°, respectively, with the pyridine and methylbenzene rings; the dihedral angle between the pyridine and methylbenzene rings is 72.19 (1)°. In the crystal, molecules are connected by weak C—HF, C—HO and C—HN hydrogen bonds. Weak C—Hπ interactions and π–π stacking [centroid–centroid distance = 3.6485 (14) Å] are also observed. The overall packing shows a three-dimensional architecture. The crystal structure contains a void of 51 Å3, but no solvent molecule (hexane or ethyl acetate) is located within it.
