title: Bis{2-hydroxy-imino-N'-[1-(2-pyrid-yl)ethyl-idene]propanohydrazidato}zinc(II) dihydrate.
abstract: The title compound, [Zn(C(10)H(11)N(4)O(2))(2)]·2H(2)O, was prepared by the reaction between Zn(CH(3)COO)(2)·2H(2)O and 2-hydroxy-imino-N'-[1-(2-pyrid-yl)ethyl-idene]propano-hydrazide (Hpop). The central Zn(II) atom has a distorted tetra-gonal-bipyramidal coordination geometry formed by two amide O atoms and four N atoms of two azomethine and two pyridine groups. In the crystal, complex mol-ecules form layers parallel to the crystallographic b direction. The layers are connected by O-H⋯N and O-H⋯O hydrogen bonds involving the solvent water mol-ecules.
