SYNTHESIS STUDY AND APPROACH ON BIOACTIVITY OF THE MIXED LIGAND COMPLEX OF EUROPIUM WITH L-GLUTAMIC ACID O-PHENANTROLINE

Abstract

   The mixed ligand complex of europium with L-glutamic acid and o-phenanthroline was synthesized in ethanol aqueous solution. The structure of the complex has been recognized by the elemental analysis, IR spectra and thermal analysis methods. The complex have the formula Eu(Glu)3PhenCl3.3H2O. The antibacterial activity of complex was tested in vitro against three Gram-positiveamd, three Gram-negative bacterial and one type of fungus. The results of antibacterial activity test shows that this complex exhibit excellent antibacterial ability against Staphylococcus aureus, Bacillus subtilis, Lactobacillus fermentum, Salmonea enterica, Escherichia coli and Candida albicans.
