The title Schiff base, C(19)H(24)N(2)O(3), exists in the crystal structure in the phenol-imine tautomeric form with an intra-molecular O-H⋯N hydrogen bond. The planes of the aromatic rings form a dihedral angle of 36.8 (8)°. The crystal packing is characterized by C-H⋯O hydrogen bonds and π-π stacking inter-actions [centroid-centroid distance = 3.478 (4)Å].

The title Schiff base, C(17)H(19)IN(2)O, is not planar, displaying a dihedral angle of 34.9 (2)° between the two aromatic rings. The mol-ecular conformation allows the formation of a strong intra-molecular O-H⋯N hydrogen bond with graph-set motif S(6) between the hy-droxy group and the imine N atom.

In the title compound, C(17)H(19)N(5)O(5), obtained from the condensation reaction of 4-diethyl-amino-2-hy-droxy-benzalde-hyde and 2,4-dinitro-phenyl-hydrazine, the two benzene rings are twisted by a dihedral angle of 1.75 (12)°. The nitro groups are slightly twisted with the respect to the benzene ring to which they are attached, making dihedral angles of 8.
