Three different 57Co-doped cobalt carbonyl complexes, NaCo (CO)4, Co2(CO)8, and CH3C(=O)Co(CO)3PPh3, representing a formal valence state of cobalt -1,0, and +1, respectively, were prepared and studied by emission Mossbauer spectroscopy. As a result of aftereffects of the EC decay of 57Co, Fe2+and Fe3+states could be identified in the Mossbauer spectra with hardly any dependence on the initial valence state of cobalt. This observation is explained by assuming the fragmentation of these molecules as result of the electron loss caused by the Auger ionization of the nucleogenic 57Fe atom.
