Abstract

Coincidence Mössbauer spectra of57Co-labelled [CoFe2O(CH3CO2)6(H2O)3] were determined at 78 K and 298 K with three timewindows of 0–50, 50–150 and 150–300 ns. Temperature dependence in the spectral shape ascribed to an intramolecular electron transfer was observed in all the time-window spectra, while little time dependence was observed. The results indicate that57Fe atoms produced by EC-decay are incorporated in a chemical environment similar to that of the parent57Co atoms, forming a trinuclear FeIIFe2 III structure at an early stage after the EC-decay.
