Abstract
The electronic states of cobalt iron cyanides were observed using Fe-5 7 Mossbauer. It was revealed that Prussian blue analogs Co-1.5[Fe(CN)( 6)]6H(2)O and K0.5Co1.25[Fe(CN)(6)]3.6H(2)O 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)]6H(2)O, a magnetic hyperfine interaction was observed at low temperature. Moreover, the Mossbauer spectra provided clear ev idence for an internal electron transfer from Fe-II to Co-III in K0.5C o1.25[Fe(CN)(6)]3.6H(2)O by red light illumination at low temperature.
