Notes:
Head-head coupling of a dimethylfulvene ligand occures in the reaction of 6,6-dimethylpentafulvene (1a) with [(C5H5)Co(C2H4)2] (7) to give (1,1,2,2-tetramethyl-1,2-ethanediyl)bis(cobaltocene) (8a). In contrast, the mononuclear η4-fulvene complexes 3b, c are obtained from 6-ethyl-6-methyl-(1b) and 6,6-diethylfulvene (1c) and 7. The crystal structures of 8a and the corresponding bis(ferrocene) 9a have been determined. The electrochemical behaviour of 8a and 9a shows 8a+, 8a-, and 9a+ to be localised mixed-valence species. Molecular mechanics calculations have been performed on the title complex and related derivatives.
