Abstract:
In the title compound, C15H13NO4, the dihedral angle between the substituted benzene rings is 9.9 (8)°. Part of the molecule (the salicylaldimine segment) is disordered over two sets of sites, with a refined site-occupancy ratio of 0.550 (14):0.450 (14). Intramolecular O—H⋯N hydrogen bonds form S(6) ring motifs. In the crystal, pairs of O—H⋯O hydrogen bonds link molecules into centrosymmetric dimers with R22(8) ring motifs. The crystal packing also features C—H⋯π interactions.
