N′-[(E)-(3-Fluoro­pyridin-2-yl)methyl­idene]benzohydrazide monohydrate

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—H...N, N—H...O and O—H...O hydrogen-bond inter­actions between the solvent water and the benzohydrazide mol­ecules, as well as C—H...O hydrogen bonds and C—F...π [3.0833 (18) Å] inter­actions.
