Preparation and identification of new Chalcone- Azo ligand (SACAI) and its complexes.

Abstract

A new organic ligand (Chalcone-azo ligand), (2E)-1-(4-((4,5-diphenyl-1H-imidazol-2-yl)diazenyl)phenyl)-3-(2-hydroxyphenyl) prop-2-en-1-one (SACAI) with its divalent (Co, Ni and Cu) complexes were synthesized. The azo-derivative was prepared via the preparation of amino chalcone first, then diazoating of this amine and coupling with (4, 5-diphenylimidazole) component. Three transition metal ion complexes were prepared from this legend, after the determination of (M: L) ratio beyond the ultraviolet-visible studies of the (ligand-ion) mixtures. The M: L ratios for all complexes were (1:2). The amino-chalcone, new ligand (SACAI) and its complexes were identified with the available techniques such (Mass spectroscopy for the ligand, elementary analysis, Atomic Absorption, UV-Visible spectroscopy, F.T.I.R spectroscopy), electrical molar conductivity and Magnetic susceptibility for the solid complexes. From the results obtained, we can suggest the non-ionic octahedral geometry for all complexes. The new ligand acting as a bidentate chelating ligand that coordinating from the N3 imidazole atom and the far azo heterocyclic ring nitrogen atom.
