In the title compound, C13H14N2O3, the dihydropyridazine ring (r.m.s. deviation = 0.166 Å) 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—H∙∙∙O hydrogen bonds generate C(5) chains and N—H∙∙∙O hydrogen bonds produce R2²(8) motifs. These types of interactions lead to the formation of layers parallel to (12). The three-dimensional network is achieved by C—H∙∙∙O interactions, including R24(8) motifs. Intermolecular interactions were additionally investigated using Hirshfeld surface analysis and two-dimensional fingerprint plots. The most significant contributions to the crystal packing are by H∙∙∙H (43.3%), H∙∙∙C/C∙∙∙H (19.3%), HO/HO (22.6%), CN/NC (3.0%) and H∙∙∙N/N∙∙∙H (5.8%) contacts. C—H∙∙∙π interactions and aromatic π–π stacking interactions are not observed. [ABSTRACT FROM AUTHOR] |
