Synthesis and Structural Properties of Copper(II), Nickel(II) and Cobalt(II) Complexes with 2,4-Furyliminobenzylacetophenone

Abstract

The new Schiff base ligand (FIAS) 2,4-furyliminobenzylacetophenone has been synthesized with 4-aminoacetophenone and furane-2-carboxaldehyde by condensation in ethanol. Metal complexes of the ligand were prepared with chloride salts of copper(II), nickel(II) and cobalt(II) in ethanol. The ligand and its metal complexes have been characterized by microanalysis, magnetic susceptibility, FTIR, 1 H and 13 C NMR, mass spectrum, and UV-visible spectroscopy techniques. From these findings, it is suggested that metal ion coordinate by imines nitrogen and carboxylic oxygen atoms of FIAS to form octahedral geometry. All the newly compounds were tested antimicrobial activity against bacterial and fungal species.
