摘要：

Pyrolysis of {Ru-3(mu-dppm)(CO)(9)}(n)(dppa) (n = 1 or 2) afforded Ru-3(mu(3)-PPhCH2PPh2)(mu(3)-eta(1):eta(2):P-C2PPh2)(mu-PPh2)(Ph)(CO)(6), containing an Ru-3 chain bridged by a dephenylated dppm ligand and by C2PPh2 and PPh2 ligands derived from the dppa ligand. The phenyl group from the dppm ligand has been trapped by one of the Ru atoms to give a rare example of a cluster-bound sigma-Ph group. The molecular structure of Ru-3(mu-H){mu(3)-eta(1),eta(2)-CCHP(O)Ph-2}(mu-PPh2)(mu-dppm)(CO)(6), obtained on one occasion from the mono-cluster complex, is also described.
