Abstract EN

This work included the preparation of the ligand )Z -N-(1-((E)-(4,5-diphenyl-1H-imidazol-2- yl)diazenyl)phenyl)ethylidene)-4-Chloro aniline (DPIDCA ) 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 with 4-chloro aniline in absolute 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,Hg ) were prepared for this new ligand ,after the fixation of the optimum condition(concentration ,pH values and mole ratio ).

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 techniques , 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.
