摘要

In the title compound, C13H10FN3O2, the mol-ecule has an E conformation with respect to the C=N bond of the hydrazone bridge. The dihedral angle between the isonicotinoyl and fluoro-phenol moieties is 4.03?(4)°, and an intra-molecular O—H?N hydrogen bond generates an S(6) ring motif. In the crystal, mol-ecules are linked by N—H?N and C—H?N hydrogen bonds, forming chains propagating along the a-axis direction. The chains are linked by C—H?O hydrogen bonds, resulting in the formation of layers lying parallel to the ab plane. The crystal structure also features π–π inter-actions [centroid-to-centroid distance = 3.6887?(8)??].
