Abstract

Abstract : 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 ({C13 H8 }‐O) upon single electron transfer from Sm II I2 (thf)2 . The dianion was obtained as a decanuclear, deca‐9‐fluorenolato, tetraoxido mixed‐oxidation‐state samarium cage [Sm10 O4 {(C13 H8 )‐O}10 (thf)10 ], obtained after ligand redistribution. The structure is relevant to the deoxygenation of ketones by lanthanoid metals.
