Emission Mössbauer spectroscopy in ⁵⁷Co doped metal acetylacetonates of Al(III), Cr(III), Mn(III), Fe(III) and Co(III)

Abstract

Metal acetylacetonates of Al(III), Cr(III), Mn(III), Fe(III) and Co(III) were doped with high specific activity carrier free ⁵⁷Co²⁺ and their emission Mössbauer spectra taken against enriched Na₄Fe(CN)₆. In the case of Al(III), Cr(III) and Co(III) complexes a simple quadrupole split pattern is obtained, while with Mn(III) and Fe(III) acetylacetonates the spectra corresponds to that of ⁵⁷Co(AcAc)₃. These results have been discussed.
