A New Pentadentate Ligand Forms Both a Di- and a Mononuclear MnII Complex: Electrochemical, Spectroscopic and Superoxide Dismutase Activity Studies

Résumé

The X-ray crystal structure of the dinuclear complex[1(PF6)2] derived from a new ligand bearing both imidazole and phenolato moieties, namely N-(2-hydroxybenzyl)-N,N'-bis[2-(N-methylimidazolyl)methyl]ethane-1,2-diamine (LH), is described and its properties in organic solvent (CH3CN) investigated (EPR, electrochemistry). [1(PF6)2] is shown to be a mononuclear MnII species in aqueous solution and displays an efficient SOD-like activity, as measured by the McCord-Fridovich assay performed both in conventional phosphate buffer and in a noncoordinating buffer (PIPES).
