摘要

The bowl-shaped hydrocarbon hexakis(E)-3,3-dimethyl-1-butenyl- benzene (HB) has been cocrystallized with either C_(60) or C_(70) to form clamshell-like assemblies with the fullerenes residing within the concave surfaces of two HB molecules. The structures of these two crystals have been determined by singlecrystal X-ray diffraction. The HB molecules exhibit back-to-back stacking and close contacts in both cocrystals. This trait is remarkably similar to the packing seen in cases in which fullerenes cocrystallize with M~(II)(OEP), where OEP is the dianion of octaethylporphyrin and M is generally Ni or Co. The C_(60) structure features an ordered cage with a disordered solvent position, while the C_(70) structure exhibits two orientations of the cage, all other components being ordered.
