Dichlorido{N'-[phen­yl(pyridin-2-yl-[kappa]N)methyl­idene]isonicotinohydrazide-[kappa]2N',O}zinc

The title compound, [ZnCl2(C18H14N4O)], crystallizes with two mol­ecules in the asymmetric unit, which differ in the tautomeric (neutral and zwitterionic) forms of the coordin­ating organic ligand. In both mol­ecules, the ZnII 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.
