Vibrational spectra of cyclopentadienyltrimethylplatinum(IV)

The Raman spectra of cyclopentadienyltrimethylplatinum(IV) in the solid state and solution have been recorded and interpreted in conjunction with the corresponding infrared spectra over the range 4000-30 cm-1. Assignments have been made on the basis of local symmetry. Polarized Raman lines at 561 and 263 cm-1 have been assigned to symmetric Pt-CH3 stretching and Pt-cp stretching vibrations respectively. The spectral data are consistent with a pentahapto π-bonded cp ring
