  • Kealy and Pauson1 have described the preparation of bis-cyclopentadienyl iron, (C5H5)2Fe, which they formulated as (I). More recently, Wilkinson, Rosenblum, Whiting and Woodward2 have observed that the compound is diamagnetic, that it has zero dipole moment, and that only one C—H stretching frequency occurs (at 3.25 µ) in the infra-red absorption spectrum; on the basis of these observations they have proposed the very unorthodox structures (II) or (III). In the present communication we wish to… CONTINUE READING
