| Abstract | ||
| New azo thiazole dye ligand 5-[(6-Bromo-2-benzothiazolyl)azo]-4-hydroxy benzoic acid(6-BrBTABA=LH2), was prepared by coupling reaction between (6-Bromo-2- benzothiazole diazonium) chloride with 4-hydroxy benzoic acid in alkalin alcoholic solution .Sixe new chelat complexes of Cr(ш),Co(п),Ni(п),Cu(п),Zn(п),Cd(п)and Ag(І) have been synthesized and characterized by element alanalysis ,molar conductance , magnetic susceptibility measurements at room temperature , infrared and electronic spectra . The analytical data show that the metal to ligand ratio (M:L)were 1:2 chelats with Cr(п) ,Co(п) and Ni(п) metal ions but 1:1 chelates with the Zn(п) ,Cd(п) and Ag(I) metal ions . | ||
