| Outline of Final Research Achievements |
While rotating polyanions have been acknowledged as significantly promoting cation transport in solid matter, the high temperature required to activate rotation has been a practical drawback. In this study, we proposed transition-metal hydride complexes with high hydrogen coordination as a new class of rotatable polyanions. By means of a combined theoretical and experimental approach, we succeeded in capturing the emergence of "pseudorotation" that is expected to lead to a development of new solid-state ionics.

| Academic Significance and Societal Importance of the Research Achievements |
これまでイオン伝導体として全く認識されていなかった遷移金属錯体水素化物において、新たな固体イオニクスの獲得にも繋がる重要な知見を得た。本研究成果は水素化物関連分野の発展のみならず、全固体二次電池関連の広範な学問分野における新たな研究領域開拓に貢献できるものと期待される。
