The title compound, C13H10FN3O·H2O, exists in the E conformation with respect to the azomethane C=N double bond. The molecule is close to planar with a maximum deviation of 0.286 (2) Å. The pyridine ring is essentially coplanar with the central C(= O)N2C unit [dihedral angle = 2.02 (3)°] and the phenyl ring exhibits a dihedral angle of 14.41 (10)° with respect to the central unit. The crystal structure features O—HN, N—HO and O—HO hydrogen-bond interactions between the solvent water and the benzohydrazide molecules, as well as C—HO hydrogen bonds and C—Fπ [3.0833 (18) Å] interactions.

The title compound, C21H18N2O3, exists in the E conformation with respect to the azomethane C=N double bond. The central benzene ring is almost coplanar with one of the substituent benzene rings [dihedral angle = 1.74 (5)°] and is approximately orthogonal to the other benzene ring of the molecule [dihedral angle = 86.61 (7)°]. An intramolecular O—HN hydrogen bond occurs. The crystal packing is dominated by N—HO hydrogen bonds, which lead to an infinite chain running parallel to [010].
