Preparation and characterization of some chelate complexe with new bi-dentate (N,O)‎ bis-schiff base ligand

Abstract EN

In this research newchelation complexes were prepared for Cr(III), Mn(II), Co(II), Ni(II) and Cu(II) ions with new bis schiff base ligand [2-(-((4-(-1-(2-phenylhydrazono)ethyl)phenyl)imino)methyl)phenol](M-Sal).

The new ligand chracterized depends on (Uv-Vis, IR) spectroscopies, 1H-NMR andMass spectra.

The results of flame atomic absorption indicate that (Metal:Ligand) portions were (1:1) for Cr(III), Ni(II) and Cu(II) complexes and were (1:2) for Mn(II) and Co(II) complexes.

The geometries of prepared complexes suggested according to the results of Uv-Vis and IR spectroscopies, magnetic susceptibility, molar conductance and flame atomic absorptionwhich were squar plannar for Ni(II)and Cu(II) complexes while the rest complexes have the octahedral geometry
