In the title compound, C27H22N2O4, the dihedral angles between the central benzene ring and the cyanobenzene ring and the 2H-coumarin ring system (r.m.s. deviation = 0.014 Å) are 22.95 (11) and 75.59 (8)°, respectively. Both terminal C atoms of the pendant diethylamino group lie to the same side of the coumarin ring system [deviations = 1.366 (2) and 1.266 (2) Å]. In the crystal, molecules are linked by C—HO and C—HN hydrogen bonds and a C—Hπ interaction, generating a three-dimensional network.

In the title compound, C14H12ClNO4S, the dihedral angle between the chloro- and methoxy-substituted benzene rings is 87.40 (1)°. In the crystal, adjacent molecules form inversion-related dimers through strong N—HO hydrogen bonds, generating R22(8) loops. The dimers are further connected through two C—HO interactions that form C(11) chains and R22(14) loops. Aromatic π–π stacking interactions [centroid–centroid separation = 3.8574 (1) Å] are also observed.

In the title compound, C15H15NO4S, the dihedral angle between the methyl- and methoxy-substituted benzene rings is 88.99 (12)°. An intramolecular C—HO hydrogen bond occurs. In the crystal, adjacent molecules form inversion-related dimers through strong N—HO hydrogen bonds, generating R22(8) loops. The dimers are further connected through C—HO interactions that form C(8) chains parallel to (001). Molecules are also connected through other C—HO hydrogen bonds along the b axis, forming additional C(8) chains. Two aromatic π–π stacking interactions [centroid–centroid separations = 3.6150 (1) and 3.6837 (1) Å] generate a three-dimensional architecture.

In the title compound, C15H13F3N2O2·H2O, the dihedral angle between the benzene and pyridine rings is 74.97 (1)°. The –CF3 group attached to the benzene ring is syn to the C=O bond in the adjacent side chain. In the crystal, molecules are linked to one another through the water molecules by strong N—HO, O—HO and O—HN hydrogen bonds, forming a ladder-type network. The benzamide molecules are also linked to one another through C—HF interactions, forming C(6) chains parallel to the b-axis direction. Aromatic π–π stacking interactions [centroid–centroid separations = 3.7150 (1) and 3.7857 (1) Å] between adjacent pairs of pyridine and benzene rings are also observed, resulting in a three-dimensional architecture are also observed.
