title: Dichlorido{N'-[phen-yl(pyridin-2-yl-κN)methyl-idene]isonicotinohydrazide-κ(2)N',O}zinc.
abstract: The title compound, [ZnCl(2)(C(18)H(14)N(4)O)], crystallizes with two mol-ecules in the asymmetric unit, which differ in the tautomeric (neutral and zwitterionic) forms of the coordin-ating organic ligand. In both mol-ecules, the Zn(II) atom adopts a distorted square-pyramidal geometry by two N and one O atoms of the Schiff base ligand and two Cl atoms acting as monodentate chloride anions. The crystal packing is stabilized by N-H⋯N and N-H⋯Cl hydrogen bonds, forming a two-dimensional network parallel to the ac plane.
