(E)-N-[(E)-3-(4-Nitro­phen­yl)allyl­idene]naphthalen-1-amine

In the title compound, C₁₉H₁₄N₂O₂, the dihedral angle between the mean planes of the 4-nitro­phenyl ring and the naphthalene ring system is 12.79 (2)°. The imine group displays a C—C—N=C torsion angle of 41.0 (2)° and the C=N group has an E conformation. In the crystal, weak C—H...O hydrogen bonds link molecules into layers parallel to the b axis.

(E)-N-(3,3-Di­phenyl­allyl­idene)naph­thal­en-1-amine

The title compound, C₂₅H₁₉N, adopts an E conformation about the C=N bond. The naphthalene ring system and the phenyl rings form dihedral angles 38.1 (1), 46.9 (8) and 48.5 (1)°, respectively, with the mean plane of the central enimino fragment. The crystal packing exhibits no directional close contacts.
