Reaction of vanadocene(II) ( 4 ) with 2,2′‐bipyridine ( 5 ) leads to (2,2′‐bipyridine)vanadocene(II) ( 6 ), exhibiting a η 3 ,η 5 ‐metallocene unit, proved by X‐ray diffraction. By selective one‐electron oxidation employing [Cp 2 Fe]BPh 4 salts, the cationic (2,2′‐bipyridine)vanadocene(III) derivative 7 is formed. It is characterized by a classical bent bis(η 5 ‐cyclopentadienyl)vanadium(III) structure. Characteristic structural details comparing changes in the oxidation states are discussed. The ring‐slip parameters are compared to those of tungsten and other vanadium complexes. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
