In the present communication a synthesized ligand 4-[2-(1-methyl benzimidazolyl) azo] proline (MBP) was used to prepare three new complexes of Cu(II), Ag(I) and Au(III). The ligand and its complexes were characterized by elemental analysis (CHN), A.A, UV-Vis, FTIR and HNMR spectroscopy, magnetic susceptibility measurement and molar conductivity measurement. Chloride ion content was also evaluated by Mohr method. The result show that the ligand was N,N-bidentate. The preparation of the complexes was conducted after fixing the optimum concentration and pH. UV-Vis spectra of these complex solutions were investigated studied for a range of pH (5-9) and concentration (1×10-5-3×10-5) which obey Lampert-Beers Law. The stoichiometry of the complexes was deduced according to mole ratio and Job methods which were obtained from spectroscopic studies of the complex solutions. The ratio of metal: ligand have been obtained were (1:2) for Cu(II) and Ag(I) complexes while Au(III) complex has (1:1) mole ratio. The antibacterial activates for the ligand and its complexes were test.
