Abstract
The title compound, C22H15N3O2, can be described as a ketone with a phenol substituent and a terpyridine ligand coordinated to the carbonyl group. The three six-membered rings of the terpyridine ligand are not coplanar. The dihedral angles between the mean planes of the central ring and the external pyridine ligands are 22.77 (9) and 26.77 (7)°. The central ring of the terpyridine ligand is also not coplanar with the o-hy-droxy phenyl ring, the dihedral angle being 39.72 (5)°. An intra-molecular O-H⋯O hydrogen bond occurs. The crystal structure of the title compound is consolidated by C-H⋯O and C-H⋯N hydrogen bonding inter-actions.

Summary
Pyridine and derivatives play critical roles in the biochemical field. The quest for an efficient method for the preparation of such pyridine derivatives is ongoing. We report a novel method for the preparation of a 2-benzoylpyridine derivative in a one-pot reaction of 3-aminocoumarin with 4-acetylpyridine. It crystallizes in the orthorhombic crystal system in P212121 space group with one molecule in the asymmetric unit. The compound can be described as a ketone with a phenol substituent and a terpyridine ligand coordinated to the carbonyl group.
