N′-[(E)-1-(2-Fluorophenyl)ethylidene]pyridine-4-carbohydrazide
The title compound, C(14)H(12)FN(3)O, 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)N(2)CC unit, resulting in a non-planar molecule. The intermolecular interact...

Sumario: | The title compound, C(14)H(12)FN(3)O, 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)N(2)CC 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. |
