Özet

The asymmetric unit of the title compound, C 21H 13N 3O 2, contains two independent molecules with a similar structure. In one molecule, the central benzene ring is oriented with respect to the terminal benzene rings at 27.23 (7) and 67.96 (7)°; in the other molecule, the corresponding dihedral angles are 12.42 (7) and 64.55 (7)°. In both molecules, there is a short O - H⋯N interaction involving the OH group and the adjacent N atom. In the crystal, there are O - H⋯N hydrogen bonds, and C - H⋯O and N - H⋯O interactions linking the molecules to form a three-dimensional network. π-π stacking between the pyridine and benzene rings and between the benzene rings [centroid-centroid distances = 3.989 (2), 3.705 (2) and 3.607 (2) Å] may further stabilize the structure. A weak C - H⋯π interaction is present in the crystal.
