Synthèse, caractérisation de nouveaux ligands base de Schiff dérivé de disulfure de carbone et étude de leur pouvoir antibactérien

Abstract

Here is the refined and corrected English version of the scientific text: In this study, four new Schiff base compounds (L1, L2, L3, and L4) and three thiosemicarbazone complexes were synthesized with good yields. The molecular structures of the synthesized compounds and their Cu(II)-L2, Co(II)-L3, and Ni(II)-P3 complexes were identified and characterized using physicochemical methods, infrared (IR) spectroscopy, and UV-Visible spectroscopy. Furthermore, the Schiff base ligands and their metal complexes were tested for their antibacterial activity. The results clearly demonstrate that the complexes are significantly more effective than the free ligands against the tested bacterial strains.
