Abstract :
Five new metal complexes of the ligand 2-amino acetate - 6 - bromo benzothiazole with some metal ions Ni(II),
Cu(II), Sn(II) Zn(II), and Cd(II) were synthesized and evaluated for their anti-bacterial activity. The prepared
complexes were characterized by 1H, Fourier transform infrared spectra, UV-Visible spectroscopy, magnetic
moment, and conductivity measurement. The spectral study showed that all the complexes obtained as
monomeric structures and central metal moieties are four–coordinated, with tetrahedral geometry, except for
the copper complex, which had square planar geometry. All the complexes showed moderate activity against
Gram-positive and Gram-negative pathogenic bacteria using disc diffusion method.
