| description | In the title compound, C17H19N5O5, obtained from the condensation reaction of 4-diethylamino-2-hydroxybenzaldehyde and 2,4-dinitrophenylhydrazine, 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 8.20 (15) and 5.78 (15)°. An intramolecular O—H...N hydrogen bond occurs. In the crystal, molecules are linked by pairs of intermolecular N—H...O hydrogen bonds, forming dimers through R22(12) rings. These dimers are further linked by C—H...O and C—H...π and weak slipped π–π interactions [centroid–centroid distance = 3.743 (2)Å]. One of the ethyl groups is disordered over two positions, with occupancy factors in the ratio 0.72:0.28. |
