The molecule of the title compound, C₁₅H₁₃O₂N₃·H₂O, is nearly planar, with an intramolecular N...O hydrogen bond of 2.616 (2) Å. It exists in the phenol–imine form and the dihedral angle between the two aromatic ring systems is 1.04 (5)°. An unsolvated form, crystallized from the same medium, has also been reported [Odabąsoglu, Albayrak & Büyükgüngör (2005). Acta Cryst. E61, o425–o426].
