چکیده
The title compound, C14H12FN3O, adopts an E conformation with respect to the azomethine bond. The pyridyl and fluoro-benzene 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 mol-ecule. The inter-molecular inter-actions 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 inter-actions are augmented by a weak π-π inter-action between the benzene and pyridyl rings of neighbouring mol-ecules, with a centroid-centroid distance of 3.9226 (10) Å. This leads to a three-dimensional supra-molecular 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 fluoro-benzene ring.
