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, 5diphenylimidazole)
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.
