摘要：
Reaction of CP*2NdCl center dot LiCl.2thf (1) with excess catecholborane affords the hexameric cluster (Cp*NdCl2)(6)(LiCl)(3)(thf)(3) (2) bearing three types of bridging chloride ions. Heating the reaction mixture affords the tetrameric cluster [(Cp*NdCl2)(4)(mu(4)-Cl)](2)[LiO2][LiO2*Li2O*O-2] (3), which has the first crystal structure with the LiO2+ motif. Reaction of complex 1 or the analogous Sm complex, 4, with pinacolborane affords clusters 5a (Nd) or 5b (Sm), respectively, it second type of hexameric cluster built from two CpNd3Cl5(thf) units bonded by two mu(2)-Cl atoms.
