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.
