Abstract: The title compound, C14H12FN3O, adopts an E conformation with respect to the azomethine bond. The pyridyl and fluoro­benzene rings make dihedral angles of 38.58 (6) and 41.61 (5)° respectively with the central C(=O)N2CC unit, resulting in a non-planar mol­ecule. The inter­molecular inter­actions comprise two classical N-H...O and N-H...N hydrogen bonds and four non-classical C-H...O and C-H...F hydrogen bonds. These inter­actions are augmented by a weak [pi]-[pi] inter­action between the benzene and pyridyl rings of neighbouring mol­ecules, with a centroid-centroid distance of 3.9226 (10) Å. This leads to a three-dimensional supra­molecular assembly in the crystal system. The F atom is disordered over two sites in a 0.559 (3): 0.441 (3) ratio, through a 180° rotation of the fluoro­benzene ring.
