The analytical and spectral data supported the binuclear formulation of the complexes with a 2:1 metal to ligand ratio and octahedral geometry. The molar conductance values of the UO2 (II)-complexes revealed their nonionic character. The ligands and their complexes were screened for their antibacterial activities towards the gram-positive Staphylococcus aureus and the gram-negative Escherichia coli, as well as their antifungal activities against Aspergillus niger and Candida albicans, in order to assess their antimicrobial potential. The results showed that metallization increases antimicrobial activity compared with the free ligands. |
