Synthesis and151Eu- and57Fe-Mössbauer spectroscopic studies of new europium-iron complexes

155Gd Mössbauer Spectroscopic Study of GdM(CN)6 · 4H2O (M = CrIII, FeIII and CoIII) and KGdM(CN)6 · 3H2O (M = FeII and RuII)

“…KLnM(CN) 6 · 3H 2 O is a substitutional derivative of LnM(CN) 6 · 4H 2 O, in which the potassium ions replace statistically half of the zeolitic water molecules [7][8]. 57 Fe and 151 Eu Mössbauer spectroscopic studies of these rare-earth cyano assembled metal complexes have been reported by several groups [9][10][11][12][13]. The 57 Fe Mössbauer parameters, especially quadrupole splitting (Q. S.), give useful information on the distortion of the octahedral iron sites [9].…”
