A rare, low‐spin Fe IV imide complex [(pyrr 2 py)FeNAd] (pyrr 2 py 2− =bis(pyrrolyl)pyridine; Ad=1‐adamantyl) confined to a cis‐divacant octahedral geometry, was prepared by reduction of N 3 Ad by the Fe II precursor [(pyrr 2 py)Fe(OEt 2 )]. The imide complex is low‐spin with temperature‐independent paramagnetism. In comparison to an authentic Fe III complex, such as [(pyrr 2 py)FeCl], the pyrr 2 py 2− ligand is virtually redox innocent.
