3-(4-Fluorophenyl)-1,5-di-2-pyridylpentane-1,5-dione

Abstract

The title compound, C21H17FN2O2, was prepared by the reaction of 4-fluoro­benzaldehyde and 2-acetyl­pridine in N,N-dimethyl­formamide under microwave irradiation. In the molecular conformation, there are three planes: a benzene plane and two pyridine planes. The dihedral angles between the benzene plane and the pyridine planes are 88.38 (15) and 83.27 (13)°, and the dihedral angle between the two pyridine planes is 8.05 (10)°. There is an intramolecular C—H⋯N hydrogen bond. In the crystal structure, a supramolecular structure is constructed by the dimeration of two molecules via an intermolecular C—H⋯O hydrogen bond.
