Spin cross-over and the Mössbauer emission spectrum of cobalt-57-labelled di-isothiocyanatobis(1,10-phenanthroline)-iron(II) and -cobalt(II)

Abstract

Mössbauer emission spectra of 57Co-labelled [Co(phen)2(NCS)2](phen = 1.10-phenanthroline) and 57Co-doped [Fe(phen)2(NCS)2] have been recorded at room temperature and at 77 and 4 K, and compared with the absorption spectrum of [Fe(phen)2(NCS)2]. A large proportion, sometimes >95%, of the emission corresponds to high-spin [57mFe(phen)2(NCS)2], irrespective of the temperature. However, both the absorption and emission spectra of [Fe(phen)2(NCS)2] vary in an unexplained manner with the method of preparation of the sample.
