title: Connectivity patterns of two C90 isomers provided by the structure elucidation of C90Cl32.
abstract: Two for the price of one: The first halogenated derivative of C(90), C(90)Cl(32) (see structure; gray C, green Cl), is obtained by chlorination of a higher fullerene mixture with SbCl(5). Its molecular structure, elucidated by single-crystal X-ray diffraction, reveals the presence of two isomeric C(90) cages that correspond to C(2v) isomer 46 and C(s) isomer 34. The addition of 32 chlorine atoms is the maximum degree of chlorination achieved for fullerenes.
