| Abstract The new ligand 2-[(6-nitro - benzo thiazolyl) azo]-hydroquinon (6-NO2BTAHQ=LH2) was prepared by coupling reaction between (6-nitro-2-benzothiazolyldiazonium) chloride with quinol in alkaline alcoholic solution.Six new chelate complexes of Zn(II), Cd(II), Hg(II), Ga(III), In(III) and Tl(III) have been synthesized. These complexes were prepared after fixing the optimum conditions of pH and molar concentration by studying Uv-vis. Spectra of the solutions that mixing the metal ions with the ligand solution in a wide ranges pH = 4.5-9.0 and molar concentration that obeyed Lambert-Beer's law. The structures of the prepared complexes have been characterized by using the molar ratio method for the metal: ligand, which is (1:2), the ligand and its complexes were investgatal by using element analysis, molar conductance measurement, stability constant ( ), Uv-vis., infrared spectra and mass spectrum of the ligand. Atomic absorption, flame emission spectrophotometer was used to determined the precents of metal ions in the prepared complexes. | ||
