Abstract
In this study we present the properties of a trinuclear ferric oxo-complex derived from the reaction of ionophorous antibiotic salinomycinic acid with Fe(II) ions. It was characterized by IR, EPR and M?ssbauer spectroscopies, and thermogravimetric analysis. The data reveal the oxidation of Fe(II) to Fe(III) during the isolation of the final product and the involvement of salinomycin as a monoanion bridging metal ions. The effect of Fe(III) ions on the antibacterial efficacy of the parent ligand was assessed towards a panel of three Gram-positive microorganisms: Bacillus subtilis, Bacillus cereus and Kocuria rhizophila.
