description The crystal of the title compound, 0.6C(14)H(12)N(2)O(3)·0.4C(14)H(12)N(2)O(3), 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.
