Resum

The reaction between [Cp2Ti(C≡CtBu)2] (1) and [cis-Pt(C6F5)2(THF)2] gives the mixed complex [Cp2-Ti(μ2-η1-C≡C tBu)2Pt(C6F5)2] (2), which has been shown by X-ray crystallography to contain a system of two asymmetric μ2-η1-alkynyl ligands bridging both metal centers. Complex 2 crystallizes as the dichloromethane solvate in the monoclinic crystal system, space group P21/n, with a = 133.725 (2) Å, b = 15.875 (2) Å, c = 16.424 (3) Å, β = 99.58 (2)°, V = 3529 (1) Å3, and Z = 4. A model of 447 parameters was refined to 3586 diffraction data, giving residuals of R = 0.0390, Rw = 0.0558, and quality-of-fit = 1.367. The Pt-Ti distance is 2.831 (2) Å. © 1993 American Chemical Society.
