N′-[(E)-1-(2-Fluoro­phen­yl)ethyl­idene]pyridine-4-carbohydrazide

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 π–π 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.
