N′-(2-Hydroxy-3-methoxybenzylidene)pyrazine-2-carbohydrazide monohydrate
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 Sch...
