Preparation and characterization one new azo compound and complexes with metal ions (Hg+2and Cd+2,Zn+2,Cu+2,Ni+2,Co+2, Fe+2,Mn+2)

Abstract

The aim of work is the synthesis and characterization of the new Ligand 2-[(4-carboxy methylene phenyl ) azo ]-4,5-diphenyl imidazole (CMPAI) . and eight chelate complexes of its Ligand with (Mn+2, Fe+2, Co+2, Ni+2, Cu+2,Zn+2,Cd+2 and Hg+2) .The structure of all complexes were deduced according to the mole ratio method .The ratio of metal : ligand (M:L) obtained (1:2) and stability constant has been founded by technique above named. All compounds have been characterized by spectroscopic methods [FT.IR.,UV-Vis] and molar conductivity measurements.(UV-Vis) absorption spectra showed bathochromic shift compared with that of free ligand . The FT.IR. spectra of these complexes showed some change in the bands and density compared with that of free ligand .Conductivity measurements have showed all complexes non-electrolyte. From the above data the proposed geometry around all ions with ligand is Octahedral
