Abstract
The chlorinated fullerenes C~78~(2)Cl~18~ and C~78~(3)Cl~18~ were synthesized by highly selective chlorination of the individual isomers. They were crystallized as C~78~(2)Cl~18~⋅Br~2~⋅TiCl~4~ and solvent free C~78~(3)Cl~18~. The carbon connectivities of both isomers have been confirmed through X‐ray single‐crystal analysis. Studious investigation of both crystal packings together with the crystal structure of C~78~(4)Cl~18~ has revealed the presence of unusually short intermolecular halogen–halogen contacts, which provide evidence for attractive intermolecular interactions, the nature of which is discussed.
