| Abstract: This work contains the preparation of the new ligand )Z -N-(1-((E)-(4,5-diphenyl-1H-imidazol-2-yl)diazenyl)phenyl)ethylidene)-4-Bromoaniline(DPIDBA)via coupling of diazonium salt of 4-amino acetophenone with the heterocyclic ring 4,5 diphenyl imidazole in alkaline alcoholic media as preliminary step , then the yield of the coupling reaction was refluxed with4-bromo aniline in ethanol , to produce a new azo-schiff (azo-azomethine) derivative . In addition, six of chelating complexes of the transition metal divalent ions (Co, Ni, Cu, Zn, Cd and Hg) were prepared for this new ligand, after the fixation of the optimum condition (concentration, pH values and mole ratio percent). The results indicate that the mole ratio (M: L) are (1:2) for all the prepared complexes. The preparing ligand (Azo- Schiff ) and its complexes were identified with the available technique , such (mass spectroscopy , elementary analysis, Atomic absorption ,UV-Visible spectroscopy , I.R spectroscopy ,electrical molar conductance and magnetic susceptibility for the complexes in its solid form .From the results obtained , octahedral geometry is the predicted geometry for all chelating complexes. | ||
