文摘

The dinuclear ruthenium(II) complex [Ru₂(CO)₂Cl₄(THT)₂(μ-THT)₂], 1, (THT = tetrahydrothiophene) exhibiting bridging thioether ligands yields mononuclear complexes upon treatment with Lewis bases by cleavage of the respective thioether bridges. Reacting 1 with an excess THT leads to the isolation of [RuCl₂(THT)₄], 2, whereas the reaction with triphenylphosphane produces the mononuclear ruthenium compound [RuCl₂(CO)(THT)(PPh₃)₂], 3. The latter compound was also characterized by X-ray diffraction.
