| Abstract | ||
| In this paper, Novel imine-complexes of Ca(II) and Mg(II) cations were synthesized and characterized. IR, TGA, UV/Vis, and 1HNMR techniques were used in conjunction with elemental (CHN), molar conductance and magnetic susceptibility experiments for characterization. None of the complexes are electrolytes, as shown by the conductivity measurements. All metal complexes exhibit diamagnetism, according to magnetic susceptibility data. Divalent cations favor a metal:ligand ratio of 1:1, depending on the analysis. Biological studies revealed that each compound had strong antimicrobial activity against a broad range of bacterial and fungal species. Furthermore, we observed that the antibacterial effectiveness of the M(II) complexes was arranged as follows: MgB > CaB > H2B. The Mg(II) combination was found to be the most effective against Gram-negative bacteria and to have the largest inhibition zone (25 mm). The following describes the antibiotic efficacy against the fungus Aspergillus flavus: MgB > CaB > H2B. According to this study, the produced substances have a high level of biological activity and may be useful in the fight against illnesses. | ||
