Synthesis, Characterization of Transition Metal (Mn, V) based Silverton Type Anion and its Antioxidant and Antimicrobial Studies

Transition metals (Mn, V) based oxo-anions (hybrid materials) were synthesized and characterized by X-ray powder diffraction, UV-visible and infrared spectral analysis. Metal-based polyoxo anion (POM) hybrid materials reflect stronger antioxidant potential as indicated by their higher DPPH scavenging activity. The synthesized POM compounds also exhibit enhanced bacterial activity of 21 ± 2 and 17 ± 3 µg/mL against Staphylococcus aureus (Gram-positive) and Escherichia coli (Gram-negative), respectively. The efficacy of the synthesized hybrid materials can be attributed to the synergistic effects of the cations and oxo-anions, which lead to more potent derivatives with a broader spectrum of antibacterial activity.
