| Research Abstract |
This study aimed to synthesize the eta9-coordinated complex using sumanene and its application to nitrogen fixation. The curved indene structure of sumanene is considered to have an advantage to form the eta9-coordinated complex when the eta5-coordinated metallocene of 4-group metals is reduced. The mononuclear and trinuclear sumanenyl metallocene complexes were synthesized from the corresponding sumanenyl anions. The obtained mononuclear zirconocene complex was treated with reductant, and nitrogen fixation was investigated. Although the products were not identified, this work is considered to contribute to the eta9-coordinated complex formation and its application to nitrogen fixation.
