Cover Picture (Angew. Chem. Int. Ed. Engl. 10/1986)

The cover shows a model for the structure of novel gold, rhodium, and ruthernium modifications: 13 metal atoms form a cluster; 13 clusters assemble to form the “supercluster” (M 13 ) 13 ; finally, n superclusters come together to form microcrystallites. These clusters were not discovered by chance, but in an investigation into the existence of small closed‐shell clusters lacking protecting peripheral ligands. M 55 clusters with ligands may be degraded electrochemically to naked M 13 clusters; the species (M 13 ) 13 and [(M 13 ) 13 ] n were then identified by means of their Debye‐Scherrer diffraction patterns. Further details are reported by G. Schmid et al. on p. 922.
