25_10/1986The 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” (M13)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. M55 clusters with ligands may be degraded electrochemically to naked M13 clusters; the species (M13)13 and [(M13)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.
