The [FeIV (O)(Me3 NTB)]2+ (Me3 NTB=tris[(1-methyl-benzimidazol-2-yl)methyl]amine) complex 1 has been shown by Mossbauer spectroscopy to have an S=1 ground state at 4 K, but is proposed to become an S=2 trigonal-bipyramidal species at higher temperatu

A novel hydroperoxoiron(III) species [Fe III (OOH)(MeCN)(PyNMe 3 )] 2+ (3) has been generated by reaction of its ferrous precursor [Fe II (CF 3 SO 3 ) 2 (PyNMe 3 )] (1) with hydrogen peroxide at low temperatures. This species has been characterized b

The Fe(TPA) (TPA = tris(pyridyl-2-methyl)amine) class of non-haem Fe catalysts is proposed to carry out selective hydrocarbon oxidations through the generation of high-valent iron species. Using ambient mass spectrometry, we obtain direct evidence fo

An unprecedentedly reactive iron species (2) has been generated by reaction of excess peracetic acid with a mononuclear iron complex [FeII(CF3SO3)2(PyNMe3)] (1) at cryogenic temperatures, and characterized spectroscopically. Compound 2 is kinetically
