Abstract
In the molecule of the title compound, C10H10N2O2, the rings are nearly coplanar, making a dihedral angle of 2.35 (5)°. In the crystal structure, intermolecular C—H⋯O, C—H⋯N and O—H⋯O hydrogen bonds link the molecules, generating R 4 4(22) and R 4 4(24) ring motifs to form a three-dimensional network. A weak π–π interaction between the pyridazinone and benzene rings further stabilizes the crystal structure, with a centroid–centroid distance of 3.709 (3) Å and an interplanar separation of 3.312 Å.
