摘要：

The diene compounds [Hf(eta-4-CH2=CMeCMe=CH2)(PMe3)2Cl2] 1, [M(eta-4-C6H8)(PMe3)2Cl2] (M = Zr 2 or Hf 3) and the divalent [Zr(eta-6-C6H5Me)(PMe3)2Cl2] 5 have been prepared. The structure of compound 1 has been determined by low-temperature neutron diffraction (15 K) and the sigma-2, pi-nature of the bonding mode of the 2,3-dimethylbutadiene ligand demonstrated from the methylene hydrogen positions. Treatment of 1 with lithium indenide gave [Hf(eta-5-C9H7)2(eta-4-CH2=CMeCMe=CH2)] 4. The crystal structure of 5 has been determined by X-ray diffraction.
