The cover picture shows the molecular structures of three novel 2,2′‐dithiobiphenyl‐ligated [2Fe‐2S] clusters together with some of their characteristic spectroscopic data. Specifically tailored capping ligands with different substituents in the 3,3′,5,5″positions ( t Bu, H, Cl) have been applied in order to examine the influence of the ligands on the electronic structures of the [2Fe‐2S] cluster cores. The article by F. Meyer et al. on p. 3219 ff demonstrates that the ligand modifications impose significant changes to the fundamental properties of the clusters, e.g. to their redox potentials. Electrochemical and spectroscopic data in solution and in the solid state (including X‐ray structures) are discussed in detail in this contribution.
