Synthesis Physiochemical Studies And Antimicrobial Screening Of Metal Complexes Of FeIII 26 AuIII With Amino Acids.

Abstract Mixed ligand complexes of IronIII and AuIII with succinimide or 8-hydroxyquinoline as primary ligands and amino acids as secondary ligands have been synthesized. The general formula of these complexes are follows KFeL2L2682422 26 AuQ L268242 where L C4H4O2N1-5 Q C9H6NO 6-10 L268242C6H12NO2 19 C6H10N2O4S226 C3H6O2NS3 C3H6NO3 47 C9H10O2N 58. The complexes were prepared in the solid form and characterization by elemental analysis conductivity magnetic moment measurement IR 1H NMR and electronic spectroscopic studies. The antibacterial and antifungal activities of the ligand and metal complexes have also been investigated. The value of 10 Dq was found to be 12250-13965 cm-1 for all complexes. The value of B 26946 and ligand field stabilization energy have also been calculated from the bands obtained in the electronic spectra of the complexes. Electronic and other measurements confirmed their octahedral and square planar structures. The metal complexes showed stronger antibacterial and antifungal activities than the ligand
