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.
