Hydride-Bridged Heterobimetallic Complexes of Zirconium and Aluminum
摘要:
Treatment of [Cp2ZrCl2] with LiAlH4 and then [H3GaL] or of preformed [Cp2ZrH2] with [H3AlL] affords the heterobimetallic complexes [Cp2ZrH(mu H)(2)AlH2(L)] (L = quinuclidine (1), NMe3 (2)). Density functional calculations gives an energy of association of ''Cp2ZrH2'' and ''H3AlNH3'' of -28.8 kcal mol(-1); cf. -28.8 kcal mol(-1) for two Cp2ZrH2 units.
