Chemistry of vinylidene complexes. XXII. Synthesis and physicochemical properties of the binuclear vinylidene complex [Cp(CO)2ReCu(μ-Cdouble bond; length as m-dashCHPh)(μ-Cl)]2. Molecular structure of the new rheniumcopper complex

The interaction between Cp(CO)2Redouble bond; length as m-dashCdouble bond; length as m-dashCHPh (1) and CuCl results in the new heterometallic μ-vinylidene complex [Cp(CO)2ReCu(μ2-Cdouble bond; length as m-dashCHPh)(μ2-Cl)]2 (2) characterized earlier by IR and 1H, 13C NMR spectra. The molecular structure of compound 2 has been determined by X-ray diffraction analysis, revealing a dimer structure with two binuclear fragments linked to each other by asymmetric chloride bridges. The electrochemical behavior of 2 in acetonitrile was studied by cyclic voltammetry at a Pt-electrode.
