A new azo-chalcone ligand was prepared in this work, by
preparation the amino-chalcone first followed by diazoted it and
reacting with the coupling component (2-naphthol) at 0?C to
produce the new ligand (VACAN).
Three chelating complexes of divalent transition metal ions (Co,
Ni, Cu) were prepared after the fixation of optimal condition of
(concentration and pH values)and determination the mole ratio
(M:L),the result indicate that the mole ratio for Co
ion
was(2:1),while the others has (1:1)ratio.
Both the amino-chalcone, the new ligand (VACAN) and its
complexes was identified with the available techniques such (Mass
spectroscopy (for VACAN), elementary analysis, Atomic Absorption,
Uv-Visible spectroscopy, I.R spectroscopy), electrical molar
conductivity and Magnetic susceptibility for the solid complexes.
From the results obtained we can suggest an octahedral geometry
for cobalt complex, square planner geometry for nickel complex
and tetrahedral geometry for copper complex was appeared.
