N′-(2-Hydroxy-3-methoxybenzylidene)pyrazine-2-carbohydrazide monohydrate
In the title hydrated Schiff base, C(13)H(12)N(4)O(3)·H(2)O, 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, O(w)—H⋯O and O(w)—H⋯N (w = water) hydrogen bonds link the components into centrosymmetric tetramer...
