Zusammenfassung: | Transition Metal Complexes of Mn(II),Co(II) and Ni(II) with Schiff base derived from 4- chloroaniline and Salicylaldehyde were synthesized and characterized by conductivity measurement, magnetic susceptibility, infrared spectra, metal-ligand ratio determination and solubility test. The Schiff base and its metal complexes were tested for antibacterial activity against Staphylococcus aureus and Escherichia coli and fungal activity against Aspergillus flavus and Mucor species. The low molar conductance values range (16-28.1Ohm- cm2 mol-1) indicated that all the complexes are non electrolytes. The magnetic susceptibility revealed that all the complexes are paramagnetic in nature. The metal-ligand ratio was found to be 1:2 in all the complexes. The infrared spectra suggested that the Schiff base behaves as a bidentate ligand. The antimicrobial studies revealed moderate activity against the tested organism when compared with the standards (Ciprofloxacin and Ketoconazole), and this activity increases by increasing concentration. And also the Metal Complexes showed higher activity than free Ligand due to chelation.Keywords: Salicyldehyde, 4-chloroaniline, Mn(II), Co(II), Zn(II) complexes, antimicrobial activity |
