| Outline of Final Research Achievements |
In the previous research on metal cluster compounds, only neutral / anionic (acidic) thiol ligands were used in the synthesis, and due to the difficulty of synthesis, there are no examples of synthesis using basic / cationic ligands. In this study, we applied the original synthetic strategy established up to now and succeeded in synthesizing a metal composition metal cluster having a basic substituent such as a pyridyl group for the first time. The use and development of metal clusters as It was shown that the ordinary surface has a unique layered packing structure based on the interaction between pyridyl groups and Na cations, unlike clusters with neutral or acidic substituents.

| Academic Significance and Societal Importance of the Research Achievements |
これまでの金属クラスター化合物研究では、合成には中性・アニオン性(酸性)のチオール配位子のみが用いられ、合成の困難さから塩基性・カチオン性の配位 子を用いた合成例はなかった。本研究では、これまでに確立してきたオリジナルの合成戦略を応用し、ピリジル基などの塩基性置換基を有する分子組成金属クラ スターの合成に初めて成功し、表面に機能性部位を持つ超分子素子としての金属クラスターの利用展開が視野に入った。
