Abstract
The title compound, C19H12N2O3, has two independent molecules (A and B) in the asymmetric unit. There is an intramolecular O—H⋯N hydrogen bond in each molecule. The mean planes of the naphthalene [maximum deviations = 0.024 (3) and 0.030 (3) Å in A and B, respectively] and the isoindoline units [maximum deviations 0.009 (3) and 0.008 (3) Å in A and B, respectively] are almostly coplanar, with dihedral angles of 4.25 (9) ad 3.84 (9)° in molecules A and B, respectively. The two independent molecules are connected by π–π interactions [centroid-centroid distances 3.5527 (19) and 3.5627 (19) Å]. In the crystal, the A+B pairs are further connected via π–π interactions [centroid–centroid distances = 3.693 (2)–3.831 (2) Å], leading to the formation of columns propagating along the a-axis direction. The columns are linked via C—H⋯O interactions, leading to the formation of a three-dimensional network.
