Synthesis, Characterization and Antifungal Activities of Some Mn(III) Mixed Ligand Complexes

Mixed ligand complexes of Mn (III) with general chemical formula [ Mn(acac)2XSH2] X=NCS- , N3 - , Cl- , Brwere synthesized in the presence of Acetyl acetone, Hydrochloric acid, Hydrobromic acid, Potassium thiocynate, Sodium azide and Hydrogen sulphide. The structures of synthesized complexes were determined by magnetic susceptibility, electrical conductivity and spectral (UV and IR) studies. The magnetic moment values of synthesized complexes indicate the presence of four unpaired electrons. The electronic conductivity data show the non-electrolytic in nature. Our results indicate the octahedral nature of Mn (III) complexes. The synthesized complexes were also screened for their antifungal activity against the fungal strains As per gillusflav us and Cladosporiumherbarium.
