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.

Academic Significance and Societal Importance of the Research Achievements

サンドイッチ構造は、遷移金属錯体における最も重要な分子構造概念のひとつである。本研究では、このサンドイッチ構造の概念を発展させることを目指した。複数の金属原子をサンドイッチ構造内に組み込むことにより、サンドイッチクラスター及びライスボールクラスターの開発に成功した。
