Abstract: In the title zwitterionic compound, C16H12N2O, the dihedral angle between the phenyl ring and the naphthalene ring system is 17.85 (8)°; an intramolecular N-H...O hydrogen bond occurs. In the crystal, [pi]-[pi] stacking is observed between naphthalene ring systems of adjacent molecules, the centroid-centroid distance being 3.6486 (11) Å.
