Distinguishing axial and equatorial carbonyl groups in iron pentacarbonyl by ESCA

Gas phase spectra were recorded for iron carbonyl. The raw spectra were analyzed using the nonlinear least-squares fitting program GAMET. The spectral data are in qualitative agreement with the prediction that the equatorial oxygen atoms are more negatively charged than the axial oxygen atoms. It is...

Zusammenfassung:Gas phase spectra were recorded for iron carbonyl. The raw spectra were analyzed using the nonlinear least-squares fitting program GAMET. The spectral data are in qualitative agreement with the prediction that the equatorial oxygen atoms are more negatively charged than the axial oxygen atoms. It is also indicated that the back-bonding to the equatorial CO groups is greater than that to the axial CO groups. (BLM)
