| Outline of Final Research Achievements |
Polyoxometalates are a large class of metal-oxygen cluster molecules of early trandition metals such as vanadium and tungsten. They can act as inorganic ligands to stabilize several kinds of metal cores into their frameworks.
The water- and temperature-triggered reversible structural transformation between cubane- and planar-type tetranuclear cobalt cores sandwiched by tungsten-based polyoxometalates, was demonstralted.
Vanadium-based polyoxometalates show a wider structural diversity than tungsten-based ones. The structures between di- abd -tri manganese and cobalt core containing vanadium-based polyoxometalates were reversiblly controled. In addition, the multimetal core of two kinds of metals was stabilized in the polyoxometalate framework.
