| Summary: | In the title hydrated Schiff base, C13H12N4O3·H2O, the dihedral angle between the aromatic rings is 5.06 (11)° and an intramolecular O—H...N hydrogen bond closes an S(6) ring. In the crystal, Ow—H...O and Ow—H...N (w = water) hydrogen bonds link the components into centrosymmetric tetramers (two Schiff bases and two water molecules). Longer N—H...O hydrogen bonds link the tetramers into [010] chains. A weak C—H...O hydrogen bond and aromatic π–π stacking between the pyrazine and phenyl rings [centroid–centroid separations = 3.604 (2) and 3.715 (2) Å] are also observed. |
