Abstract

High versus low: The high-yield generation of a synthetic high-spin oxoiron(IV) complex, [FeIV(O)(TMG3tren)]2+ (see picture, TMG3tren = 1,1,1-tris{2-[N2-(1,1,3,3-tetramethylguanidino)]ethyl} amine), has been achieved by using the very bulky tetradentate TMG 3tren ligand, in order to both sterically protect the oxoiron (IV) moiety and enforce a trigonal bipyramidal geometry at the iron center, for which an S=2 ground state is favored.
