Axial ligand substituted nonheme FeIV=O complexes: observation of near-UV LMCT bands and Fe=O Raman vibrations.

چکیده
Axial ligand substitution of a mononuclear nonheme oxoiron(IV) complex, [FeIV(O)(TMC)(NCCH3)]2+ (1) (TMC = 1,4,8,11-tetramethyl-1,4,8,11-tetraazacyclotetradecane), leads to the formation of new FeIV=O species with relatively intense electronic absorption features in the near-UV region. The presence of these near-UV features allowed us to make the first observation of Fe=O vibrations of S = 1 mononuclear nonheme oxoiron(IV) complexes by resonance Raman spectroscopy. We have also demonstrated that the reactivity of nonheme oxoiron(IV) intermediates is markedly influenced by the axial ligands.

Protein-free and protein-containing chlorosomes from Chloroflexus aurantiacus, strain 0k -70fl, were studied by resonance Raman (RR) spectroscopy. Both preparations gave the same spectra o f the bacteriochlorophyll c (BChl c) chromophores in the range o f 12001750 cm “1. This strongly corroborates previous evidence [Griebenow et al., Z.

High valent non-heme iron-oxygen species, such as Fe=O adducts, have been proposed as key intermediates for numerous non-heme iron enzymes. However, only one such Fe=O adduct has been detected in an enzyme system. In contrast, synthetic complexes containing non-heme Fe=O units have been generated using a variety of supporting ligands, and these studies have already demonstrated that the coordin...
