摘要：

The reaction between [Cp2Ti(C=C(t)Bu)2] (1) and [cis-Pt(C6F5)2(THF)2] gives the mixed complex [Cp2-Ti(mu2-eta1-C=C(t)Bu)2Pt(C6F5)2] (2), which has been shown by X-ray crystallography to contain a system of two asymmetric mu2-eta1-alkynyl ligands bridging both metal centers. Complex 2 crystallizes as the dichloromethane solvate in the monoclinic crystal system, space group P2(1)/n, with a = 133.725 (2) angstrom, b = 15.875 (2) , c = 16.424 (3) angstrom, beta = 99.58 (2)-degrees, V = 3529 (1) angstrom3, and Z = 4. A model of 447 parameters was refined to 3586 diffraction data, giving residuals of R = 0.0390, R(w) = 0.0558, and quality-of-fit = 1.367. The Pt-Ti distance is 2.831 (2) angstrom.
