Abstract

The trigonal-bipyramidal high-spin (S = 2) oxoiron(IV) complex [Fe IV(O)(TMG 2dien)(CH 3CN)] 2+ (7) was synthesized and spectroscopically characterized. Substitution of the CH 3CN ligand by anions, demonstrated here for X = N 3 - and Cl -, yielded additional S = 2 oxoiron(IV) complexes of general formulation [Fe IV(O)(TMG 2dien)(X)] + (7-X). The reduced steric bulk of 7 relative to the published S = 2 complex [Fe IV(O)(TMG 3tren)] 2+ (2) was reflected by enhanced rates of intermolecular substrate oxidation.
