High versus low : The high‐yield generation of a synthetic high‐spin oxoiron(IV) complex, [Fe IV (O)(TMG 3 tren)] 2+ (see picture, TMG 3 tren = 1,1,1‐tris{2‐[N2‐(1,1,3,3‐tetramethylguanidino)]ethyl}amine), has been achieved by using the very bulky tetradentate TMG 3 tren 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.
