摘要：

The Ru=Ru double-bonded mu-alkyne complexes [Ru2(mu-CO)(mu-RC2R)(eta-C5H5)2] (R = Ph or CF3) react in heptane or xylene at reflux with alkynes R'C=CR' (R' = CO2Me or CF3) to link up to four molecules of alkyne; the structures of the complexes [Ru2(CO){mu-C4(CF3)4}(eta-C5H5)2] (two isomers) and [Ru2{mu-C8(CF3)2(CO2Me)6}(eta-C5H5)2], which contains a C6 ring with a C2 'tail', have been established by X-ray diffraction.
