36_04/1997The cover picture shows a “wheel with a hydrocarbon tire”. This is how the authors F. H. Köhler et al. describe the molecule that they isolated from the reaction of FeCl2 with tetrahydro-4,4,8,8-tetramethyl-4,8-disila-s-indacenediyl dilithium. In this hexane-soluble compound, seven ferrocene units are linked by seven pairs of Me2Si groups to form an almost regular cycle. The compound can undergo three chemically reversible oxidations in which three, one, and again three electrons are transferred. More about this fascinating “super-ferrocene” is reported on pages 387 ff.
