Comparative 57 Fe Mössbauer absorption and emission data are reported for the anhydrous and hydrated Fe(II) and Co(II) acetylacetonates in the temperature range from 1.5 to 300 K. The results concern the structural, electronic, and paramagnetic relaxation properties of the Fe 2+ ions in these hosts. The 57 Fe emission data of the 57 Co electron capture decay products show that a fraction of the decayed atoms occupies unperturbed substitutional sites whereas another part stabilizes in perturbed ferrous sites and as ferric ions.
