The cover shows the structure of the first highly symmetrical star cluster, [Ni2Pt2W43-CPh)4(CO)8(η-C5H5)4]. The drawing clearly reveals the unusual and novel structural features: tungsten (•), mickel (•), and platinum (•) form an eight-membered ring, which fixes the four phenylcarbyne ligands in a starlike formation. Ni[BOND]Pt bonds are either absent or very weak. The large cavity is empty. Further details regarding this complex and isomers with related structures are reported by F. G. A. Stone et al. on page 190.
