Synthesis and Characterization of Some New Ni, Cu and Co Complexes with Azo-Shciff Base Ligand

Abstract

Azo-schiff base lig and prepared by other obvious studies but we use special amine compound amino acid lysine, bath of azo and schiff base were characterized by FT-IR and H¹NMR spectroscopy to notice the different resulting from condensation reaction [Co (AHDB)₂] ⁺²,[ Co (AHDB)₂] ⁺² and [ Ni (AHDB)₂] ⁺² complexes with a two molecules of bidentate ligand were synthesized  and identified by using various spectroscopic techniques. Obtained difference in UV-Vis spectrum between ligand and complexes indicates on successful of complication reaction appearance of band belong to d-d transition and didn’t found in ligand spectra, another indication of complication is the H¹NMR spectrum show the same chemical shifts in both ligand and complexes cases with small shifting in ppm region which is expected result.

Keywords: Azo-schiff base ligand, Cobalt tetra coordinate complexes, Amino acid schiff base.
