The 9-fluorenone (fn) ketyl in [Yb-III(DippForm)(2)(fn-O)] {DippForm = N,N-bis(2,6-diisopropylphenyl)formamidinate}, underwent reduction to the dianion ({C13H8}-O) upon single electron transfer from (SmI2)-I-II(thf)(2). The dianion was obtained as a decanuclear, deca-9-fluorenolato, tetraoxido mixed-oxidation-state samarium cage [Sm10O4{(C13H8)-O}(10)(thf)(10)], obtained after ligand redistribution. The structure is relevant to the deoxygenation of ketones by lanthanoid metals.

Deca-9-Fluorenolato-deca-氧化钐笼

[Yb-III(DippForm)(2)(fn-O)] {DippForm = N,N-双(2,6-二异丙基苯基)甲脒}中的 9-芴酮 (fn) 酮基被还原为二价阴离子 ({ C13H8}-O) 从 (SmI2)-I-II(thf)(2) 的单电子转移。二价阴离子是作为十核、deca-9-fluorenolato、四氧化混合氧化态钐笼 [Sm10O4{(C13H8)-O}(10)(thf)(10)] 获得的，在配体重新分配后获得。该结构与镧系金属对酮的脱氧有关。
