Preparation and characterization of cadmium (ll), zinc (ll) and copper (ll) ion complexes using new triazene ligands and study of their biological activity

The synthesis of novel ligand was disclosed in this study. This ligand was synthesized from reaction between ۴-amino anti pyrene and ۶-amino penicillanic acid by triazene reaction. The ligand was identified by FT-IR, UV-Visible, HNMR, Mass spectroscopy reacting the ligand with salts of transition metals Cu, Zn, Cd (II) complexes and gave octahedral, hybridization sp۳d۲ complexes with a molar ratio (۱:۲) M:L Magnetic Para-Di complexes were produced using amoral ratio of metal chloride to ligand spectroscopic data used to establish the identity of ligand of their corresponding complexes by FT-IR, UV-VIS, atomic absorption, magnetic susceptibility and conductivity. The ligand and its complex exhibited biological activity. It gave good results in inhibiting gram positive Streptococcus bacteria.
