Reaction of Cp* 2 NdCl · LiCl · 2thf ( 1 ) with excess catecholborane affords the hexameric cluster (Cp*NdCl 2 ) 6 (LiCl) 3 (thf) 3 ( 2 ) bearing three types of bridging chloride ions. Heating the reaction mixture affords the tetrameric cluster [(Cp*NdCl 2 ) 4 (μ 4 ‐Cl)] 2 [LiO 2 ][LiO 2 *Li 2 O*O 2 ] ( 3 ), which has the first crystal structure with the LiO 2 + motif. Reaction of complex 1 or the analogous Sm complex, 4 , with pinacolborane affords clusters 5a (Nd) or 5b (Sm), respectively, a second type of hexameric cluster built from two CpNd 3 Cl 5 (thf) units bonded by two μ 2 ‐Cl atoms.
