The conformation of the title compound, C14H19N3S, is partially determined by an intramolecular N—H...N hydrogen-bond interaction, although the N—H...N angle of 108° is quite small. The cyclohexylidene ring has a chair conformation and its mean plane is inclined to the benzene ring by 46.30 (8)°. 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 reinforced by pairs of C—H...S hydrogen bonds, and are linked by further weak C—H...S hydrogen bonds, forming chains propagating along [100].

In the title compound, C12H10Cl2N2O2, the seven-membered heterocycle displays a half-chair conformation. The mean plane through the oxopropylidene group makes a dihedral angle of 36.44 (9)° with the fused benzene ring. An intramolecular N—H...O hydrogen bond to close anS(6) loop is noted. An important feature of the molecular packing are N—H...O hydrogen bonds that lead to the formation of helical supramolecular chains along thebaxis.

The N—H bond adjacent to the benzene ring issynto them-methyl groups. The dihedral angle between the benzene ring and the side chain [mean plane of atoms C—C(O)N—C—N; maximum deviation 0.029 (2) Å] is 14.30 (7)°. There is an intramolecular N—H...O hydrogen bond generating anS(6) ring motif. In the crystal, the molecules are linkedviaN—H...) hydrogen bonds, forming chains propagating along [001].

In the title compound, C18H27N3OS, the cyclohexane ring has a chair conformation. The azomethine C=N double bond has an E configuration. The nearly planar hydrazinecarbothioamide moiety and substituted benzene ring are twisted by 31.13 (5)° relative to each other. The amide moiety and the cyclohexane ring are almost perpendicular to each other; a similar conformation was previously observed in reported structures. In the crystal, molecules are linked by N—H...S hydrogen bonds, forming inversion dimers with an R 2 2(8) ring motif.

In the title compound, C19H13ClF2N2O2, the conformation of the N—H bond in the amide segment isantito the C=O bond. The molecule is not planar, with dihedral angles between the central benzene ring and the outer benzene and pyridyl rings of 73.35 (7) and 81.26 (6)°, respectively. A weak intramolecular C—H...O hydrogen bond occurs. In the crystal, N—H...N, C—H...O and C—H...F hydrogen bonds lead to the formation of dimers. The N—H...N inversion dimers are linked by π–π contacts between adjacent pyridine rings [centroid–centroid = 3.8541 (12) Å] and C—H...π interactions. These contacts combine to stack the molecules along theaaxis.

In the title compound, C9H9N3OS, the plane of the benzene ring forms a dihedral angle of 33.40 (5)° with that of the triazole group. In the crystal, molecules are linked by O—H...N hydrogen bonds involving the phenol –OH group and one of the unsubstituted N atoms of the triazole ring, resulting in chains along [010]. These chains are further extended into a layer parallel to (001) by weak C—H...N hydrogen-bond interactions. Aromatic π–π stacking [centroid–centroid separation = 3.556 (1) Å] between the triazole rings links the layers into a three-dimensional network.
