2-(6-Oxo-3,4-diphenyl-1,6-dihydropyridazin-1-yl)acetic acid

Abstract

In the title compound, C18H14N2O3, the pyridazine ring makes dihedral angles of 72.73 (11) and 49.97 (10)degrees with the two phenyl rings. The dihedral angle between the two phenyl rings is 52.42 (12)degrees. The crystal structure is stabilized by intermolecular O-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen-bonding interactions.
