摘要：

The reaction of CrCl2(PEt3)x with potassium pentadienide leads to a compound with the stoichiometry of a phosphine adduct of Cr(C5H7)2, "Cr(C5H7)2PEt3"; however, dimerization through pentadienyl-pentadienyl coupling actually leads to a Cr(I) species. Its structure has been determined and suggests little if any contribution from an enediyl Cr(III) resonance form. The structure of the known Cr(2,4-C7H11)(CH3)(dmpe) has also been determined to allow comparison with the former compound.
