Preparation and crystal structure of [μ-Ni(C5H5)P(C6H5)3] [μ-C5H5] [ZnC5H5]2, a nickel-bridged cyclopentadienylzinc dimer

Abstract

[μ-Ni(C5H5)P(C6H5)3] [μ-C5H5]2 [ZnC5H5]2 has been obtained from the reaction of Cp2Zn with Ni(COD)2 in the presence of Ph3P and its structure determined by X-ray crystallography. It consists of two cyclopentadienylzinc moieties bridged by the Ni atom of a CpNiPPh3 group and by a Cp group. A possible mechanism for the formation of the compound is discussed.
