Abstract: In the title molecule, C21H18N2O3, the pyridine rings make a dihedral angle of 13.1 (1)°. The phenyl ring is approximately perpendicular to both of them, forming dihedral angles of 87.4 (1)and 81.9 (1)°. In the crystal, pairs of O-H...N hydrogen bonds link the molecules into centrosymmetric dimers. Additional C-H...O, [pi]-[pi] [centroid-centroid distance = 3.971 (2) Å] and C-H...[pi] interactions consolidate the dimers into a three-dimensional network.
