title: Crystal structure of 4-{(E)-[2-(pyridin-4-ylcarbon-yl)hydrazin-1-yl-idene]meth-yl}phenyl acetate monohydrate.
abstract: The asymmetric unit of the title compound, C15H13N3O3·H2O, comprises a 4-{(E)-[2-(pyridin-4-ylcarbon-yl)hydrazinyl-idene]meth-yl}phenyl acetate mol-ecule and a solvent water mol-ecule linked by O-H⋯O and O-H⋯N hydrogen bonds from the water mol-ecule and a C-H⋯O contact from the organic mol-ecule. 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.
