【 摘 要 】

The asymmetric unit of the title compound, C15H13N3O3·H2O, comprises a 4-{(E)-[2-(pyridin-4-ylcarbon­yl)hydrazinyl­idene]meth­yl}phenyl acetate mol­ecule and a solvent water mol­ecule linked by O—H⋯O and O—H⋯N hydrogen bonds from the water mol­ecule and a C—H⋯O contact from the organic mol­ecule. The compound adopts an E conformation with respect to the azomethine bond and the dihedral angle between the pyridine and benzene rings is 21.90 (7)°. The azomethine bond [1.275 (2) Å] distance is very close to the formal C=N bond length, which confirms the azomethine bond formation. An extensive set of O—H⋯O, O—H⋯N, N—H⋯O and C—H⋯O hydrogen bonds builds a two-dimensional network progressing along the c axis.
