9-Pentafluorophenylmethylene-9H-fluorene

M. J. Plater, R. A. Howie and D. M. Schmidt

Abstract: The principal structural feature of the title compound, C₂₀H₉F₅, is the dihedral angle of 51.22 (5)° between the substituent phenyl ring and the fluorene fragment of the molecule. This results in the close approach of an F atom to the plane of the fluorene fragment, compromising the planarity of the latter. The conformation also permits virtually complete overlap and - interaction of the phenyl ring of one molecule with the five-membered ring of the fluorene of another, in infinite chains of head-to-tail molecules.
