摘要：
Iron mixed-valence complex, (n-C3H7)(4)N[(FeFeIII)-Fe-II(dto)(3)] (dto=C2O2S2), shows a charge transfer phase transition around 120 K and a ferromagnetic transition at 6.5 K. In order to control the charge transfer phase transition by changing the cation size, we synthesized (n-CnH(2n+1))(4)N[(FeFeIII)-Fe-II(dto)(3)] (n=3-6) and investigated the charge transfer phase transition by means of Fe-57 Mossbauer spectroscopy. The charge transfer phase transition takes place around 120 K for n=3 and 4, while it does not take place between 300 K and 4 K for n=5 and 6.
