Singly-bonded fullerene dimers: neutral (C60Cl5)2 and cationic (C70)22+ †
Abstract
C60Br24 and C70Br10 react with TiCl4, splitting out bromine, and, after Br/Cl exchange, forming singly-bonded dimeric structures (C60Cl5)2 and [(C70)2](Ti3Cl13)2, respectively, the latter consisting of dimeric [(C70)2]2+ dications and (Ti3Cl13)− anions.
