Electrochemical and Computational Chemistry Study of Mn(β-diketonato)3 complexes

摘要: Abstract Nine different Mn(β-diketonato) 3 complexes, with β-diketonato = dipivaloylmethanato, acetylacetonato, benzoylacetonato, dibenzoylmethanato, trifluoroacetylacetonato, trifluorothenoylacetonato, trifluorofuroylacetonato, trifluorobenzoylacetonato and hexafluoroacetylacetonato, were synthesized. The effect of the various substituents on β-diketonato backbone these ease oxidation reduction central metal in nine was studied by means electrochemistry. It found that, when adding aromatic to ligands reduced/oxidized species stabilized. also more electron withdrawing groups that complex easily reduced at a higher potential. Good linear relationships trends obtained between mean value peak potential Mn III /Mn II redox couple, electronic parameters DFT calculated energies.
