Back Cover: Molecular Wheels of Ruthenium and Osmium with Bridging Chalcogenolate Ligands: Edge-Shared-Octahedron Structures and Metal-Ion Binding (Angew. Chem. Int. Ed. 11/2012)

Abstract

Wheel-like assemblies are fascinating and exquisite. Anderson-type molecular wheels (structures on the periphery first proposed in 1937 and right structure) each feature six skew-edge-shared octahedra. In their Communication on page 2614 ff., C. M. Che and co-workers report selective binding of Cu+ or Ag+ by isolated [{M(S-4-R-C6H4)2(CO)2}6] (right structure to bottom-right structure) and isolation of [{M(SPh)2(CO)2}8] (bottom left), thus demonstrating feasible expansion of Anderson-type wheels to octanuclear congeners.
