Description

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 ?-? interaction between the benzene and pyridyl rings of neighbouring molecules, with a centroid-centroid distance of 3.9226(10) 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. 2014 CrossMark.
