Abstract
Coordination compounds of modified diamine, the basic unit of which are ethylenediamine, with that of Co (Ⅱ)are prepared. The modified diamines are ethylenedia-ceticacid (EDDA) and N,N,N,N-tetaraethylene-1,2-diamine (TEEDA). These diamines are characterized through 1H-NMR, 13C-NMR, elemental analysis and IR techniques. Cobalt (Ⅱ) complexes of these two ligands were prepared and characterized by physical measurements including elemental analysis, IR, UVVisible, magnetic susceptibilities and conductance measurements. Antibacterial activities are also carried out in order to investigate the biological activity upon complexation. They were screened against four pathogenic bacteria like Escherichia coli, Pseudononas aeroginosa,Klesbella pneumonia and Staphylococcus aureus. The results showed significant enhancement in activities.
