| Outline of Final Research Achievements |
We previously reported the synthesis of Fe42, a cyanide-bridged nanocage that exhibits an unusually large S = 45 spin ground state. The structure is composed of 42 Fe sites and cyano groups that enable the introduction of magnetic interactions. In this study, we replaced the Fe sites by Mn and/or Ni ions to develop new mixed-valence magnetic molecules containing hetero-metal ions that have both fascinating polyhedral structures and electronic and spin states that can be switched by external perturbation at the single cluster level. Here we report nano-sized molecular magenets that contains 18 Fe ions and 24 Mn and/or Ni ions. These molecules are mixed-valent compounds, and its mixed-valence state can be changed, yielding ferromagnetic or antiferromagnetic behavior in the 42 nuclear nanocages.
