| Abstract: | The preparation of a novel mononuclear complex of zirconium having an η8-bonded pentalene ligand and two η3-allyl groups is described. Its structure has been determined by 1H and 13C 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 C2 symmetry with the enantiomeric forms undergoing racemisation. |
