Ferrocene derivatives bearing substituents with aluminum in the 1,1′‐positions, in the absence of donor ligands, possess rather unusual structural features. Starting from various dipyridine adducts of such 1,1′‐disubstituted ferrocene derivatives, it proved possible to trap the pyridine as the adducts R 3 Al(py) and monitor the formation of dinuclear and trinuclear aluminum‐bridged ferrocenophanes in solution by NMR spectroscopy. For the first time, the dynamic behaviour of such complexes was studied and a complete set of NMR spectroscopic data has been reported. The dinuclear complex [Fe(η 5 ‐C 5 H 4 ) 2 ] 2 Al 3 Et 5 was characterized by X‐ray structural analysis. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
