The reaction between 1,1'-dilithioferrocene and 2,5-bis(chlorodimethylsilyl)thiophene (I), leads to a series of cyclic oligomers of basic formulation [Fc-SiMe 2 -TH-SiMe 2 ] n (II); Fc=(η 5 -C 5 H 4 ) 2 Fe, TH=C 4 H 2 S. The material n=2, IIa, has been completely characterized by spectroscopic and single crystal X-ray diffraction. Cyclic voltammetric analysis of IIa illustrates two reversible redox processes, indicating a significant interaction between the two ferrocenylene units despite the 5 atom bridge. By comparison, the monomeric analog Fc-SiMe 2 -TH-SiMe 2 -Fc (III), Fc=(η 5 -C 5 H 5 )Fe(η 5 -C 5 H 4 ), prepared from the reaction of mono-lithioferrocene with I, exhibits a single redox process, even though there is the same bridge between the two Fe centers.
