► Easy synthesis reaction of Sulfonamide- based complexes. ► X-ray diffraction characterization. ► Electrochemical studies of antibiotic ligands and complexes. ► Antibacterial activity studies.
Copper(II) and nickel(II) complexes of sulfadimethoxine, sulfadiazine, sulfamerazine and sulfamethazine were synthesized with a good yield according to an original procedure. These complexes were first characterized by single-crystal X-ray diffraction and electrochemistry. Structural inspections showed that the antibacterial entity of ligands remains non-coordinated to metal ions in the complex high-lighting the fact that in each cluster, antiseptic activity of the metal has been associated to the antibiotic activity of the ligand. In order to confirm this possibility, antibacterial activities of the complexes were studied on several bacteria. The antibacterial activity of the complex is as important as the ligands one with the addition of antiseptic activity
via the incorporation of copper ions. |
