Abstract: The title zwitterion,, C16H11ClN2O, is approximately planar, the dihedral angle between the benzene ring and naphthalene ring system is 1.55 (13)°; an intramolecular N-H...O hydrogen bond stabilizes the planar conformation. In the crystal, [pi]-[pi] stacking between the benzene ring and the naphthalene ring system of adjacent molecules links the molecules into supramolecular chains running along the b axis, the centroid-centroid distance being 3.765 (2) Å.
