p‐Methoxy­benz­aldehyde benzoyl­hydrazone monohydrate

The crystal structure of the title compound, C₁₅H₁₄N₂O₂·H₂O, is in the keto tautomeric form and the configuration at the azomethine C=N double bond is E. The mol­ecule is non‐planar, with a dihedral angle of 27.3 (1)° between the aromatic rings. The crystal structure is stabilized by extensive hydrogen bonding involving the water mol­ecule and hydrazone moiety.
