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
