Author(s): E.Khalkhali, H.Nabipour

The dithiocarbamate (DTC) ligands have also proven to be excellent compounds due to their extensive applications as fungicides, pesticides, vulcanization accelerators.Most of these applications are based on complexation properties of DTC ligandswithmetal ions, especiallywith transitionmetal ions. DTCligands readily formchelateswith all transition metal ions through its two donor sulfur atoms. The secondary diamine ligands, used as starting material for the preparation of the metal complexes, were obtained in 80% yield by condensation of acetophenon with 1,6- hexamethylenediamine inmethanol followed by reduction of the Schiff base withNaBH4 inmethanol.One-pot synthesis from this amine, carbon disulfide, triethylamine and CoCl2.6H2O gave colorless precipitates. The ultrasonic treatment applied for preparation nanoparticles. The antibacterial activity of nanoparticles derivatives tested against microorganism and compared with non-nano conditions. The resulting nanoparticles were characterized by X-ray diffraction (XRD), infrared spectroscopy (IR) and scanning electron microscopy (SEM).
