2,6-Bis[(2-hydr­oxy-3-methoxy­benzyl­idene)hydrazinocarbon­yl]pyridine monohydrate

In the title compound, C₂₃H₁₉N₅O₆·H₂O, the two components are linked into complex chains by a combination of two independent O—H...O and two independent N—H...O hydrogen bonds. The complex chains are linked into a two-dimensional sheet network via π–π stacking inter­actions and C—H...O hydrogen bonds.
