Coordination Behaviour of Imino Hydrazone Ligands towards Nickel (II) and Copper (II) Ions

Abstract

The complexing ability of a new series of ligands, β-N-arylimine hydrazones, toward Ni (II) and Cu (II) ions has been studied. The isolated complexes are characterised on the basis of elemental analysis, spectroscopic methods and magnetic susceptibility measurements. The ligands are notentially bidentate in character coordinating to divalent metal ions through the N¹ and N⁵ nitrogens. Square planar geometry of the metal ions is suggested on the basis of experimental evidence.
