| Abstract | ||
| A new series of organomercury compounds containing azo group were prepared from 4-acetaminophenol and mercerized aniline derivatives; include 2-(2- mercury chloride-4-X-phenyl azo)-4-acetamido phenol {X=sulfonic acid (L1), acetyl (L2), carboxy (L3), nitro (L4) and sulphamide (L5)}. All these compounds were characterized by F.T.IR-spectroscopy, 1H-NMR, Micro-elemental analysis and UVVis spectroscopic techniques. The work also involves a study of acid-base properties at different pH values, the ionization and protonation constants were calculated. The complexes of L1 and L5 with Cu(II) were prepared . These complexes have been conclude after fixing the optimum conditions (time, pH and sequence of addition effects). It was found that the complexes are 1:2 (M:L) complexes and the overall stability constants were determined by the corresponding solutions method. The spectra of the complexes solutions have been studied for a range of concentrations which Lambert-Beer's law obeyed. K | ||
