摘要: Dicyclopentadienylmagnesium, cyclopentadienylmagnesium chloride, bromide, cyclopentadienyllithium and cyclopentadienylsodium were examined by UV, IR, PMR spectroscopy in tetrahydrofuran. None of them exhibited UV maxima at >210 nm. All their infrared spectra indicated D5h, D5d or C5v symmetry. consisted sharp single peaks room temperature. The results are interpreted terms metal cyclopentadienide ion pairs which the atom lies on near C5 axis ion.
