The complete molecule of the title compound, C19H34N2S, is generated by crystallographic twofold symmetry, with the C=S group lying on the rotation axis. A short C—H
S contact occurs in the molecule. The five-membered ring is twisted and the cyclohexyl ring adopts a chair conformation. The dihedral angle between the mean plane of the five-membered ring and the basal plane of the cyclohexyl ring is 75.32 (13)°.

There are two independent molecules in the asymmetric unit of the title compound, C6H12N2S, in which the N-methylthioformamide unit and the pyrrolidine ring mean plane are oriented at dihedral angles of 5.9 (5) and 5.9 (4)°. In the crystal, zigzag C(4) chains extending along the a axis are formed due to N—HS hydrogen bonds between alternate arrangements of molecules. The chains are interlinked by C—HS hydrogen bonds.

In the title compound, C10H13N3O3, the 3,4-dimethoxybenzylidene and hydrazinecarboxamide groups are oriented at a dihedral angle of 53.82 (6)° and an intramolecular N—HN hydrogen bond generates an S(5) ring motif. In the crystal, molecules are linked by N—HO hydrogen bonds into sheets propagating in (-201), which feature R12(5), R22(8) and R24(14) loops.

In the title compound, C9H11N3O3, two molecules are present in the asymmetric unit in which the 4-hydroxy-3-methoxybenzaldehyde and hydrazinecarboxamide units are almost planar [with r.m.s. deviations 0.0212 and 0.0066 Å, respectively, in one molecule and 0.0346 and 0.0095 Å, respectively, in the other] and are oriented at dihedral angles of 9.7 (3) and 16.6 (3)°. In both molecules, two S(5) ring motifs are present due to N—HN and O—HO hydrogen bonds. In the crystal, the molecules are dimerized with each other due to pairs of N—HO hydrogen bonds, forming an R22(8) ring motif. O—HO hydrogen bonds lead to the formation of a three-dimensional network.

Two independent molecules are present in the asymmetric unit of the title compound, C12H10N2O, in which the 3-hydroxybenzaldehyde and the pyridin-3-amine units are almost planar [r.m.s. deviations of 0.0236 and 0.0116Å, respectively, in one molecule and 0.0245 and 0.0162Å, respectively, in the other] and are oriented at dihedral angles of 7.21 (7) and 14.77 (7)°. In the crystal, molecules of the same type form inversion dimers via pairs of O—HN hydrogen bonds, forming R22(20) ring motifs. There exist π–π interactions between the benzene and pyridine rings of molecules of the same type with centroid–centroid distances of 3.7127 (10) and 3.8439 (10) Å.
