Abstract

original image

Direct proof of the cage connectivities of four isomers of C96, the highest isolable empty fullerene, has been achieved. C96 fractions, which were isolated from fullerene soot by recycling HPLC, were chlorinated and the resulting single crystals of C96Cl22 and C96Cl24 were studied by X-ray diffraction using synchrotron radiation. D2-C96(183)Cl24 (see structure; gray C, green Cl) was obtained in two crystalline modifications.
