Treatment of the U(III) complex, [(C5Me5)2U(OMes)(THF)], Mes = 2,4,6-Me3C6H2, with Fe(CO)5 forms [(C5Me5)2(MesO)U}2(μ2-(OC)2Fe(CO)2)] with the bridging, tetrahedral Fe(CO)4 moiety. This complex has been studied using 1H NMR, IR vibrational, UV–vis electronic absorption, and zero-field 57Fe Mössbauer spectroscopy as well as single-crystal X-ray diffraction analysis, magnetic measurements, and DFT calculations

An anisotropic EPR spectrum observed at 20 K in γ-irradiated single crystals of Cr(CO)6 doped with Fe(CO)5 is ascribed to the radical anion Fe(CO)−5. Measurements of the g-, 57Fe-, and 13C-hyperfine tensors clearly show that the species is an acyl radical Fe(CO)−4CO in which the unpaired spin is principally located in Fe 3dz2 or 3dx2−y2 and in an sp2 hybrid of the unique carbon atom C(1). The Fe–C(1)−O(1) moiety is bent and its plane lies close to the ac crystallographic plane of Cr(CO)6.
