The organic mol­ecule of the title compound, C18H14N4O2·H2O, lies on a center of inversion located at the centre of the central phenyl­ene ring. There are two half-molecules in the asymmetric unit. In the crystal, the mol­ecules are linked through by N—H⋯O and O—H⋯N hydrogen bonds involving the water mol­ecule, forming a layer structure. The layers inter­act by π–π inter­actions between the aromatic rings.
