We report the synthesis and single crystal X-ray analysis of C 84 ( 14)ÁAgTPP (Ag tetraphenylporphyrin) cocrystal-the first ordered crystal structure containing a pristine higher fullerene.

Ein chirales Fulleren: Die erste geordnete Kristallstruktur eines Derivats des D2‐symmetrischen C76‐Fullerens, C76Cl18, wurde bestimmt. Das verzerrte Kohlenstoffgerüst von C76Cl18 enthält verlängerte C‐C‐Bindungen und ein in dieser Form einzigartiges π‐System. Der C76‐Käfig (siehe Bild; grün) ist durch zwei helicale Gürtel von Chloratomen umgeben (orange).

The chlorinated fullerenes C78(2)Cl18 and C78(3)Cl18 were synthesized by highly selective chlorination of the individual isomers. They were crystallized as C78(2)Cl18 x Br2 x TiCl4 and solvent free C78(3)Cl18. 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 C78(4)Cl18 has revealed the presence of unusually short intermolecular halogen-halogen contacts, which provide evidence for attractive intermolecular interactions, the nature of which is discussed.

Welcome to the family! The constitution of the chiral D(2)-C(80) fullerene has been confirmed through single-crystal X-ray analysis of the chlorinated C(80)Cl(12). The addition pattern of the chlorine atoms in the structure of C(80)Cl(12) together with other structures of halogenated higher fullerenes is discussed. A stepwise principle of higher fullerene reactivity is proposed. Unusual short intermolecular chlorine-chlorine contacts are reported.
