Synthesis and crystal structure of 1,1′-bis[4-(2,2′:6′,2″-terpyridin-4′-yl)phenyl]octamethylferrocene

1,1′-Bis[4-(2,2′:6′,2″-terpyridin-4′-yl)phenyl]octamethylferrocene was prepared from iron(II) chloride and lithiated 4′-[4-(2,3,4,5-tetramethylcyclopenta-1,3-dien-1-yl)phenyl]-2,2′:6′,2″-terpyridin and was structurally characterised by X-ray diffraction, which revealed pronounced π-stacking of the six-membered aromatic rings. Its electrochemistry was investigated by cyclic voltammetry and controlled potential coulometry and compared with that of related compounds.
