Abstract
Abstract In this article, a synthesized ligand [(1-phenyl-2-pyrazolin-5-one) azo (6-bromo-2-hydroxynaphthalen-1-yl)] has employed for preparing three new complexes of Co(II), Ni(II) and Cu(II). The new azo ligand (PABH) has analyzed by Micro Elemental Analysis (CHNO), UV-visible, Fourier Transform infrared (FTIR) approaches, 1H,13C-NMR spectroscopy and mass spectroscopy. The consequence has specified that the ligand was represented as N,N,O-tridentate. The preparing of complexes has accomplished after fixing the finest concentration and pH values. UV-Vis spectra of these complexes solutions have been examined for a range of pH (5-9) and concentration (1×10-4 - 5×10-4) Molar that comply with Lambert-Beers law. A stoichiometry of the complexes has comprehended in relation to mole ratio which has investigated from a spectroscopic technique. The ratio of metal: ligand was achieved with (1:2) for all complexes. The metal ions complexes were characterized by FTIR, UV-Visible, molar conductance, atomic absorption, magnetic susceptibility and elemental analysis CHNO techniques. From the results of physico-chemical and spectral techniques, octahedral geometry has been proposed for these metal complexes. All these compounds were evaluated against two kinds of human pathogenic bacteria such as Staphylococcus aureus (Gram Positive) and Escherichia coli (Gram negative).
