Some nonheme hydroperoxoiron(III) species have been recently characterized by several groups. The reported examples were obtained by adding H2O2 in excess to an FeII complex with a neutral polypyridine ligand. We show here that on deprotonation, the purple low-spin hydroperoxoiron(III) complex [L5FeIIIOOH]2+ [L5 = N-methyl-N,N',N'-tris(2-pyridylmethyl)ethane-1,2-diamine] gives a blue high-spin species which we characterized as the η2-peroxoiron(III) species [L5FeIIIO2]+. It seems that with such an auxiliary ligand, the hydroperoxo group is acidic in contrast with its basicity when it is coordinated to a heme group. |
