Europium-151 and iron-57 nuclear resonant vibrational spectroscopy of naturally abundant KEu(III)Fe(II)(CN)₆ and Eu(III)Fe(III)(CN)₆ complexes.

ABSTRACT: We have performed and analyzed the first combined ¹⁵¹Eu and ⁵⁷Fe nuclear resonant vibrational spectroscopy (NRVS) for naturally abundant KEu(III)[Fe(II)(CN)₆] and Eu(III)[Fe(III)(CN)₆] complexes. Comparison of the observed ¹⁵¹Eu vs.⁵⁷Fe NRVS spectroscopic features confirms that Eu(III) in both KEu(III)[Fe(II)(CN)₆] and Eu(III)[Fe(III)(CN)₆] occupies a position outside the [Fe(CN)₆] core and coordinates to the N atoms of the CN^- ions, whereas Fe(III) or Fe(II) occupies the site inside the [Fe(CN)₆]^4- core and coordinates to the C atoms of the CN^- ions. In addition to the spectroscopic interest, the results from this study provide invaluable in
