A new tripodal imine ligand tris(2‐(propan‐2‐ylideneamino)ethyl)amine (imine 3 tren) was prepared in order to stabilize high valent iron‐oxido complexes. Iron complexes were synthesized in template reactions from iron(II) salts, tris(2‐aminoethyl)amine (tren) and acetone. Due to the reversibility of the imine formation, complexes with different ligands were obtained depending on the reaction conditions. Three complexes, [Fe(imine 3 tren)(OAc) 2 ] ( 1 ), [Fe(imine 3 tren)(OAc)]OTf ( 2 ) and [(imine 3 tren) 2 Fe 2 (F) 2 ](SbF 6 ) 2 ( 3 ), could be synthesized and structurally characterized. However, reactions with hydrogen peroxide, iodosobenzene or ozone did not lead to any kind of “oxygen adduct” complex that could be spectroscopically observed.
