Preparation and Characterization of New Azo Ligand N-[(1-(4-(4,5-Dimethyl-1h-Imidazol-2-Yl) Diazenyl) Phenyl-3-(Trifluoromethyl)] Aniline With Some Metal Complexes Ions

Author(s): Waleed A Mahmoud, Amir Musa and Nadia H Obaid

A ligand which is derived from 4,5-diphenyl imidazole has been prepared, the co-ordination of this ligand with the metal ions of Co (II),Ni(II),Cu(II),Zn(II),Cd(II) under optimum circumstances of concentration and PH , the results have shown that the concentration of these complexes would be comply with Lambert- Beers law ,based on these results ,a mole ratio has been calculated for the complexes of the mentioned ligand ,so the ratio of (metal :ligand) has been found equal to (1:2) , as the ligand and its metal complexes has been distinguished using UV- Visible spectrum and IR spectrum , the H1 NMR has shown a harmonization with chemical formulas and the results of magnetic sensitivity of metal complexes ions has confirmed that geometric figure of octahedral.
