Abstract
An experimental and theoretical study of the transient Fe(CO)⋅/4 radical is presented. This radical, isoelectronic with Co(CO)4, is obtained for the first time in solution, by y-irradiation of dilute Fe(CO)5 at 77 K. The general features of its ESR spectrum are similar to those of Co(CO)4, i.e., a nearly axial g tensor (g∥ = 2.0039, g⊥ = 2.0707), but it was impossible to get further information on 13C couplings. On the basis of the experimental results for Co(CO)4, we present a theoretical study by both Extended Huckel and Xα-methods for Fe(CO)⋅/4 in trigonal pyramidal geometry.
