Abstract
ABSTRACT:The mixed ligands complexes of Imidazol (Im) and naphthal hydroxamic acid (NHA) with
transition metal salt of Mn(II), Fe(II), Co(II), Ni(II) and Cu(II) were prepared . they were characterized by
using (FT-IR) spectroscopy,(UV-Vis.) spectrophotometery and chlorine content test, atomic absorption
spectroscopy also by using molar conductance . this study showed that ligand Imedazol behaves as a
monodentate ligand and Naphthalhydroxamic acid as a chelating tridentate ligand , the complexes have an
octahedral geometry. The free ligands and their complexes have been tested for their antibacterial
activities against four kinds of human pathogenic bacteria: (Streptococcus paecalies, Staphylococcus
aureus), (Escherichia coli, Klebsiella Peneumonia ). the first group are Gram positive while the second
group are Gram negative by using agar well diffusion method. Finally ,it was found that compounds show
different activity of inhibition on growth of the bacteria
