  • Abstract
    In the title compound, C13H14N2O3, the dihydropyridazine ring (r.m.s. deviation = 0.166 A˚ ) has a screw-boat conformation. The dihedral angle between its mean plane and the benzene ring is 0.77 (12). In the crystal, intermolecular O—HO hydrogen bonds generate C(5) chains and N—HO hydrogen bonds produce R2 2 (8) motifs. These types of interactions lead to the formation of layers parallel to (121). The three-dimensional network is achieved by C—HO interactions, including R2 4 (8) motifs. Intermolecular interactions were additionally investigated using Hirshfeld surface analysis and twodimensional fingerprint plots. The most significant contributions to the crystal packing are by HH (43.3%), HC/CH (19.3%), HO/HO (22.6%), CN/NC (3.0%) and HN/NH (5.8%) contacts. C—H interactions and aromatic – stacking interactions are not observed
