57Fe Mössbauer, 13C{1H} NMR and IR spectroscopic investigations have been carried out on the aryliron derivatives [Fe(Ar)(CO)L(?5-C5H5)] (L = CO, Ar = C6H5, C6F5, 2-FC6H4, 2-ClC6H4 2-IC6H4, 2-CH3C6H4, 2-(C6H5CH2)C6H4 and C6H5CO; L = PPh3, Ar = C6H5, 2-FC6H4). Mössbauer isomer shifts and quadrupole splittings, 13C NMR chemical shifts and IR ?(CO) stretching force constants are presented. These data are discussed in relation to variation of the aryl ligand, Ar, and the FeC bonds. Evidence is presented for some ortho interactions between the iron and the 2-phenyl substituent and is discussed. © 1984.
