In the title compound, C19H23NO6, the 1,4-dihydropyridine ring is twisted slightly from planarity, with a maximum deviation of 0.101 (1) Å, and adopts a very flattened boat conformation. The dihedral angle formed between the plane through the four C atoms of the 1,4-dihydropyridine ring and the benzene ring is 84.67 (7)°. In the crystal structure, intermolecular N—HO and C—HO hydrogen bonds link the molecules into a three-dimensional network.

In the title compound, C6H10N2O, the 2,3-dihydro-1H-pyrazole ring is approximately planar, with a maximum deviation of 0.013 (1) Å. Pairs of intermolecular N—HO hydrogen bonds link neighboring molecules into dimers, generating R22(8) ring motifs. These dimers are further linked into two-dimensional arrays parallel to the bc plane by intermolecular N—HO hydrogen bonds. The crystal structure is further stabilized by C—Hπ interactions.

In the title compound, C14H18N2O3S, the 1H-pyrazole ring is approximately planar, with a maximum deviation of 0.005 (1) Å. The dihedral angle formed between the 1H-pyrazole and phenyl rings is 79.09 (5)°. Pairs of intermolecular N—HO and OHN hydrogen bonds form dimers between neighboring molecules, generating R22(10) ring motifs. These dimers are further linked by intermolecular N—HO and O—HN hydrogen bonds into two-dimensional arrays parallel to the ac plane. The crystal structure is also stabilized by C—Hπ interactions.
