SYNTHESIS, CHARACTERIZATION AND ANTIMICROBIAL ACTIVITY OF MIXED LIGAND COMPLEXES OF Mn(III) WITH 5- NITROSALICYLALDEHYDE AND 2-HYDROXYARYL CARBONYL COMPOUNDS OR ?-DIKETONES
Mithlesh Agrawal*, Rashmi Gaur, Swati Bugalia and Neha Jain
ABSTRACT Mixed ligand complexes of Mn(III) of the type [Mn(L)(L')2], (HL = 2- hydroxyacetophenone, 2-hydroxypropiophenone, 2- hydroxybenzophenone, pentane-2,4-dione, 1-phenylbutane-1,3-dione or 1,3-diphenylpropane-1,3-dione) and (HL’ = 5-nitrosalicylaldehyde) have been synthesized by the reaction of Manganese(III) acetate with a mixture of two different ligands in 1:1:2 molar ratios. The resulting complexes have been characterized by elemental analyses, molar conductances, magnetic moments, IR and FAB mass spectral studies. Octahedral geometry has been proposed for the prepared mixed ligand complexes. The mixed ligand complexes were also tested for their antimicrobial activity against Escherichia coli, Staphlococcusaureus and Salmonella paratyphi. Keywords: Mixed ligand complexes, Mn complexes, FAB mass, Antimicrobial Activity. [Download Article] [Download Certifiate] |
