T. Sato et al., CONVERSION OF THE VALENCE STATES OF FE-57 ATOMS PRODUCED IN CO-57-LABELED [CO(PYRIDINE)(2)NI(CN)(4)], Chemistry Letters, (12), 1997, pp. 1287-1288
Emission Mossbauer spectra of the title compound measured below 80K co
nsist of three components ascribed to two Fe(II) high-spin states and
one Fe(III) low-spin state. It was concluded that a part of the Fe(II)
high-spin species converts to an Fe(III) high-spin species above 210
K, based on the comparison of the results with temperature-depending s
pin-crossover transition of the isomorphous compound, [Fe(py)(2)Ni(CN)
(4)].
