Outline of Final Research Achievements

In this project, we aimed at developing the chemistry of molecular sandwich clusters and rice-ball clusters. We found that polycyclic aromatic compounds or hetero-arenes can be introduced at a cluster-site of a cycloheptatriene-supported metal cluster. We also found that a metal-metal edge bonds in a cyclononatetraenyl sandwich cluster provide a ligand-unsupported docking site for extra metal moieties. Furthermore, we successfully isolated and characterized the rice-ball Pd13 clusters by using cycloheptatrienyl ligands.
