Infrared, (57)Fe Moessbauer, and (31)P NMR Spectroscopic Characterization of Fe(CO)4L (L = Phosphine and Phosphite)

A series of trigonal bipyramidal Fe(CO)4L complexes has been prepared and characterized by infrared, (57)Fe Moessbauer and (31)P NMR spectroscopy.A linear correlation, with a negative slope, between the CO stretching frequencies and the isomer shifts demonstrates that the triple bond nature of the carbonyl ligands is strengthened with increasing iron-to-phosphorus back donation.The linear dependence of the quadrupole splittings on the isomer shifts with a positive slope has revealed that the ?-donor capability of the phosphine or phosphite ligand is offset by the ?-acceptor capability.The formation of Fe(CO)4L complexes from the corresponding free ligands is accompanied by a downfield shift of (31)P NMR chemical shifts.The coordination shifts are linearly correlated with the Moessbauer isomer shifts. - Phosphinetetracarbonyliron, Phosphitetetracarbonyliron, IR Spectra, (31)P NMR Spectra, (57)Fe Moessbauer Spectra
