Metal ion complexes of Co(III), Cu(II), Fe(III), Cr(III) and Ni(III) have positive effect in the development of antimicrobial properties. The ligand and the complexes have been examined for antibacterial activity against a range of Gram-positive (Bacillus authracis, Bacillus cereus, Bacilis subtilis Staphylococcus aureus, Streptococcus agalactiae) and Gram-negative bacteria (Escherichia coli, Shigella dysenteriae, Shigella sonnei). In this present study, we report here the antimicrobial properties of transition metal mixed ligand complexes. Our results are consistent with that of others.
Key words: Antibacterial activity, metal complexes, ligand.
