Molecular Structure of Fluorene
Abstract
THERE has been considerable discussion during the past thirty years or so about the shape and in particular about the planarity of the fluorene molecule. If the molecule is not flat, then there is the possibility of obtaining optical isomers with unsymmetrically substituted fluorene derivatives, and some claims have been put forward that such isomers have been resolved. A qualitative estimation of the main X-ray crystal reflexions from fluorene together with optical and magnetic data led one of us some years ago1 to the conclusion that the fluorene molecule was non-planar. The consequences in regard to optical isomerism were discussed by Cook and Iball2, who gave a brief review of the literature on the subject.
