摘要
Iron( I) in biology?: one-electron oxidation of an {Fe(I)-Fe(I)} carbonyl cyanide precursor bearing a proximal thioether group leads to an {Fe(I)- Fe(II)} bridging carbonyl transient with spectral features similar to the di-iron sub-site of the CO inhibited paramagnetic centre of all-iron hydrogenase.
