Abstract

The electronic states of cobalt iron cyanides were observed using ⁵⁷Fe Mössbauer. It was revealed that Prussian blue analogs Co_1.5[Fe(CN)₆]6H₂O and K_0.5Co_1.25[Fe(CN)₆]3.6H₂0 have Fe^III(low spin) and Fe^II(low spin), respectively, at both room temperature and 4 K. In Co_1.5[Fe(CN)₆]6H₂O, a magnetic hyperfine interaction was observed at low temperature. Moreover, the Mössbauer spectra provided clear evidence for an internal electron transfer from Fe^II to Co^III in K_0.5Co_1.25[Fe (CN)₆]3.6H₂O by red light illumination at low temperature.
