This work involves the chemical synthesis of new complexes derived from bis(5-(benzylthio)- 1,3,4-thiadiazol-2-yl)methane, and characterized by C.H.N.M. elemental analysis, FTIR spectroscopy, Electronic spectra (Uv–visible), in addition to molar conductance (
m) of complexes solution in DMF solvent , and evaluation the magnetic moments (Meff) via Gouy’s method The antibacterial activity for the ligand and their metal complexes were studied against three selected micro-organisms Staphylococcus aureus, Pseudomonas, and Klebsiella. The antibiotic Gentamycin has been chosen to compare with the ligand and complexes
