摘要:
                                Reaction of the mixed alkyl / hydride complex [Cp'Lu(CH2SiMe3)(mu-H)(THF)](2) (2; CP'= C3Me4SiMe3) with 1 equiv of PhSiH3 (per Lu) in benzene or OEt2 afforded the polyhydrido cluster [Cp'LuH2](4) (3), while hydrogenolysis of 2 with H-2 (1 atm) in THF yielded the THF-coordinated complex [Cp'Lu(mu-H)(2)](4)(THF) (4). Complexes 3 and 4 are interconvertible, without decomposition or ligand redistribution.
