Abstract

The molecular Structures of the cationic cyclic alkyl(alkoxy)carbene– and the corresponding alkoxyvinyl–nickel(II) complexes trans-{NiRL2([graphic omitted])]BF4and trans-[NiRL2([graphic omitted])](R = C6Cl5 and L = PMe3) have been determined by X-ray crystal structure analysis; a comparison of the structures suggests strong π-bonding in the nickel–carbene bond.
