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.
