摘要：
The Zr( + 3) complex of composition [Cp2Zr(mu -H)](2)(mu -H)AlCl2 (8) and the Zr(+ 4) complex of composition [Cp2ZrH(mu -H)(2)](3)Al (9) were isolated from solutions containing zirconocene(+ 4) and titanocene(+ 3) compounds and LiAlH4 and characterized by X-ray structural analysis. The basic structural element of 8 is the six-atom ring Zr2AlH3, in which the metal atoms are linked by ordinary hydrogen bridges. In the structure of 9, the H-endo(b) atom is off the bisector plane of the Cp2Zr fragment and the Al-H distances in the distorted octahedral environment of the aluminium atom are markedly different.
