Description
Summary:The complexes have been obtained by direct reaction of potassium tetrachloropalladate(II) with corresponding esters of ( S, S)-ethylenediamine- N, N′-di-2-propanoic acid. Three new ligands and their palladium(II) complexes of general formula [PdCl 2(R 2- S, S-eddp)] (R = n-propyl, n-butyl and n-pentyl) have been synthesized and characterized by microanalysis, infrared and 1H and 13C NMR spectroscopy. Antimicrobial activity of these ligands and complexes was tested by microdilution method and both minimal inhibitory and microbicidal concentration were determined. These tested complexes demonstrated the significant antifungal activity against pathogenic fungi Aspergillus flavus and Aspergillus fumigatus. On the other hand, these complexes demonstrated moderate antibacterial activity.
