A significantly flattened corannulene, which is η6-coordinated on each side by a {Cp*Ru}+ moiety, is revealed in the X-ray structure analysis of [(Cp*Ru)2266-C20H10)][PF6]2. The reaction of [{Cp*Ru(μ3-Cl)}4] with Ag+ ions and the curved-surface buckybowl corannulene (C20H10) in CD3NO2 solvent affords this dimetallated corannulene complex (see picture).
