| Summary: | The crystal of the title compound, 0.6C14H12N2O3·0.4C14H12N2O3, contains a mixture of its neutral (OH containing) and zwitterionic (NH containing) forms, in a 0.60 (4):0.40 (4) ratio. The former generates an S(6) loop via an intramolecular O—H...N hydrogen bond and the latter generates an S(6) loop via an N—H...O hydrogren bond. The aromatic rings are oriented at a dihedral angle of 42.52 (10)°. In the crystal, C—H...π interactions occur and aromatic π–π stacking interactions [centroid–centroid separations = 3.7106 (12) and 3.9177 (13) Å] consolidate the packing. |
