Synthesis and Spectral Study of 2-(1-hydrazonoethyl) Pyridine Ligand and Their Complexes with Some Transition Metal (II)

Abstract

In this study, new novel[APH=2-(1-hydrazonoethyl)pyridine] ligand; which have contained hydrazone group, and their transition metal complexes of [NiII, , ZnII and CdII] were synthesized.The (APH) ligand was synthesized by condensation of 2-Acetyl pyridine with hydrazine monohydrate, and the reaction of (APH) ligand with metal ions ratio of (2:1) respectively, were formed a mononuclear complexes with a metal(II) ions of types [M(APH)2]Cl2and [Ni(APH)₂Cl₂] when [M= NiII, ZnII, CdII].The ligand and their complexes were characterized and study on the basis of FT-IR and U.V.–visible. Some physical properties and spectral data for ligands and their complexes are given in Table 1 and 2.
