Dichlorido{N′-[phen­yl(pyridin-2-yl-κN)methyl­idene]isonicotinohydrazide-κ²N′,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 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.
