Outline of Final Research Achievements

Despite many exploratory studies over the past several decades, the transition metals that form hydride complexes had been limited to the Groups 7-12. In this study, we discovered four novel hydrides containing hydride complexes of Group 5 and 6 transition metals with ninefold hydrogen coordination. Furthermore, we demonstrated the emergence of superconductivity in the obtained hydride under high pressure.

Academic Significance and Societal Importance of the Research Achievements

主に水素貯蔵関連研究のみに限定され、また既に完結したものと見なされていた遷移金属錯体水素化物研究において、新たな研究領域の開拓にも繋がる重要な知見を得た。これにより、高い潜在性を持ちながらも機能性材料としての認識が限定的であった錯体水素化物の学術的・社会的価値を高めることに貢献した。
