Abstract

Ultrathin red plate crystals of a chiral C60-fullerene cis-3 bisadduct were subjected to X-ray crystallographic analysis to finally determine the absolute configuration of such an adduct conclusively (see picture; C gray, O red, H blue). A comparison of its circular-dichroism spectrum with those of similar compounds suggested that the absolute configurations reported for some compounds may require revision (Figure Presented).
