(E)-N′-(4-Meth­oxy­benzyl­idene)pyridine-3-carbohydrazide dihydrate

In the title compound, C(14)H(13)N(3)O(2)·2H(2)O, the hydrazone mol­ecule adopts an E conformation with respect to the C=N bond. The dihedral angle between the benzene and pyridine rings is 8.55 (10)°. The methyl­idene–hydrazide [–C(=O)–N–N=C–] fragment is essentially planar, with a maximum deviation of 0.0375 (13) Å. The mean planes of the benzene and pyridine rings make dihedral angles of 2.71 (14) and 11.25 (13)°, respectively, with mean plane of the methyl­idene-hydrazide fragment. In the crystal, the benzohydrazide and water mol­ecules are linked by N—H⋯O, O—H⋯O and O—H⋯N hydrogen bonds into a three-dimensional network.
