摘要：

The preparation of a novel mononuclear complex of zirconium having an eta(8)-bonded pentalene ligand and two eta(3)-allyl groups is described. Its structure has been determined by H-1 and C-13 NMR spectroscopy. At room temperature some of the NMR signals are broadened, revealing that the compound is structurally dynamic. It is shown that the compound has C-2 symmetry with the enantiomeric forms undergoing racemisation. (C) 1998 Elsevier Science S.A.
