Abstract : New metal complexes of the ligand Potassium (Benzothiazole-2-dithiocarbamato hydrzide) (L) with the metal ions Cr (III), Co (II), Cu (II), Pd (II) and Cd (II) were prepared in alcoholic medium. The prepared complexes were characterized by flame atomic absorption, FTIR, UV-Vis Spectroscopy, magnetic susceptibility and conductivity measurements. From these analysis, octahedral geometry was suggested for Cr (III), Cu (II) and Pd(II) complexes, while Co(II) and Cd(II) complexes have tetrahedral geometries, Structural geometries of these compounds were also suggested in gas phase by using hyper chem-6 program. PM3 was used to evaluate the vibrational spectra of the free ligand and these obtained frequencies agreed well with those values experimentally found. The antibacterial activity for the starting material, the ligand and its metal complexes were studied against two selected microorganisms staphylococcus aureus and pseudomonas aeruginosa using two different concentrations (10 & 5mM) in nutrients agar medium.
