Dichlorido{N0-[phenyl(pyridin-2-yl-jN)- methylidene]isonicotinohydrazidej2 N0 ,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—HN and N—HCl hydrogen bonds, forming a twodimensional network parallel to the ac plane.
