N'-[(E)-(3-Fluoro-pyridin-2-yl)methyl-idene]benzohydrazide monohydrate.

The title compound, C(13)H(10)FN(3)O·H(2)O, exists in the E conformation with respect to the azomethane C=N double bond. The mol-ecule is close to planar with a maximum deviation of 0.286 (2) Å. The pyridine ring is essentially coplanar with the central C(= O)N(2)C 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 inter-actions between the solvent water and the benzohydrazide mol-ecules, as well as C-H⋯O hydrogen bonds and C-F⋯π [3.0833 (18) Å] inter-actions.
