Spectroscopic study of derivatives of cyclo-pentadienylirondicarbonyl, containing an iron-tin bond

Conclusions

  1. 1.

    The IR spectra in the region of the frequencies of the valence vibrations of CO and the proton magnetic resonance spectra of a series of derivatives of cyclopentadienylirondicarbonyl, containing a tin-iron bond, were studied.

  2. 2.

    On the basis of the data obtained on the frequencies, relative intensities of the IR bands, and the values of the chemical shifts in the NMR spectrum, the mechanism of transmission of the influence of substituents on the tin atom to the carbonyl ligands and protons of the cyclopentadienyl ring, as well as possible conformations of derivatives of the type of [C5H5(CO)2Fe]2SnX2, are discussed.
