- Synthesis, structure, and reactions of heterobinuclear μ-methylene complexes
-
Sources of the reactive fragment Cp2Ti==CH2 react with a variety of late-transition-metal complexes containing μ-halides [Cl-MLn]2 to yield early-late binuclear complexes containing μ-CH2, and μ-Cl ligands. Complexes containing Rh, Ir, Pt, Pd, and Au have been prepared and characterized. The X-ray structure of the complex Cp2Ti-CH2-RhCl(COD) (COD = 1,5-cyclooctadiene) prepared from Cp2Ti-CH2C-(CH3)2-CH2 and [Cl-Rh(COD)]2 has been determined. Crystallographic data: space group Pbcm; Z = 4; a = 8.268 (2) A?, b = 16.409 (4) A?, c = 12.604 (3) A?; V = 1710 (1) A?3. The structure was refined to a final R of 0.069 and R3σ of 0.048 for the 1061 reflections that had Fo > 3σ(Fo).
