摘要：

An improved synthesis of the heterodimetallic complex [RuMn(mu-H)(mu-PPh2)(eta-5-C5H5)(CO)5] 1 is described and the reactions of this complex with alkynes RC = CR (R = Ph, H or CO2Me) and with tertiary phosphines have been studied. Complexes containing mu-alkenyl ligands are obtained from the reaction of 1 with alkynes and the crystal structure of one of these, [RuMn{mu-sigma:eta-2-C(Ph) = CHPh}(mu-PPh2)(eta-5-C5H5)(CO)4] has been determined by X-ray analysis; the alkenyl ligand is sigma-bonded to Ru and pi-bonded to Mn, while the PPh2 group asymmetrically bridges the Ru-Mn bond [2.729(2) angstrom]. Tertiary phosphines react with 1 to give complexes which are monosubstituted at the manganese atom.
