The asymmetric unit of the title compound, C30H46N6O4, contains one half-molecule. The C(benzene)—C(CH2)—N—C(—Me) torsion angle is −79.89 (13)° suggesting a synclinal orientation of the nitrobenzene ring with respect to the macrocycle. The conformation of the macrocycle is stabilized by intramolecular N—H

In the title compound, C19H23N, the piperidine ring has a chair conformation. The phenyl rings are inclined to one another by 52.76 (16)°. One of the methyl substituents on the piperidine ring is axial while the other is equatorial, like the phenyl rings. In the crystal, molecules are linked via C—Hπ interactions, forming zigzag chains along [001].

In the title compound, C16H14O4, there is an intramolecular O—HO hydrogen bond. The benzene rings are inclined to one another by 13.89 (9)°. The prop-2-en-1-one group is twisted slightly, the O=C—Car—Car (ar = aromatic) and C=C—C=O torsion angles being −10.4 (3) and −7.4 (3)°, respectively. In the crystal, molecules are linked by O—HO hydrogen bonds, forming chains along [100]. These chains are further linked by O—HO hydrogen bonds, forming corrugated sheets lying parallel to (010). There are C—Hπ interactions present within the sheets.

In the title compound, C16H14O4, the benzene rings are inclined to one another by 4.91 (7)°. The conformation about the C=O and C=C bonds is trans and cis, respectively. In the crystal, molecules are linked by O—HO hydrogen bonds, forming inversion dimers with an R22(14) ring motif. The dimers are linked via O—HO and C—HO hydrogen bonds, forming undulating two-dimensional networks lying parallel to (10-1). These networks are linked by further C—HO hydrogen bonds, forming a three-dimensional structure.
