Heterocycles as Ligands, X 1) . — 2,2′,5,5′‐Tetra‐ tert ‐butyl‐1,1′‐diazaferrocene – Stabilization of the Diheterometallocene Structure by Steric Shielding Stable 2,2′,5,5′‐tetra‐ tert ‐butyl‐1,1′‐diazaferrocene ( 3 ) is obtained by the reaction of the corresponding lithiopyrrole with FeCl 2 . The X‐ray analysis reveals a distorted sandwich structure influenced by repulsive interactions presumably both between the nitrogen atoms and the bulky tert ‐butyl substituents.
