Synthesis of New Complexes by Using Pyridine Acetohydrazone Derivatives

Abstract

A new ligand L₁=[N-(1-pyridine-2-yl)Ethlidene AcitoHydrazide]; was synthesized by condensation of acetohydrazide with Acitil pyridine. Then the complexes were synthesized by reacting the transition metals (Co²⁺,Cr³⁺ , Fe²⁺) with the ligand [ with a metal to ligand ratio of (1:2) respectively]  and this led to forming the following complexes : [Co(L₁)₂] Cl₂ , [Cd(L₁)Cl], [Fe(L₂)SO₄] .The ligands and complexes were characterized and studied on the basis of FT-IR, and U.V.–visible and the results were compatible with the proposed structures

Keywords: ligand, metal complexes, pyridine.
