Abstract

A rare, low-spin FeIV imide complex [(pyrr2py)Fe[DOUBLE BOND]NAd] (pyrr2py2−=bis(pyrrolyl)pyridine; Ad=1-adamantyl) confined to a cis-divacant octahedral geometry, was prepared by reduction of N3Ad by the FeII precursor [(pyrr2py)Fe(OEt2)]. The imide complex is low-spin with temperature-independent paramagnetism. In comparison to an authentic FeIII complex, such as [(pyrr2py)FeCl], the pyrr2py2− ligand is virtually redox innocent.
