Mi. Bruce et al., CODIMERISATION OF CO AND A 1,3-DIYNYL-METAL COMPLEX ON AN RU-3 CLUSTER, Journal of the Chemical Society. Dalton transactions, (14), 1996, pp. 3151-3152
The reaction of [W(C=CC=CH)(CO)(3)(cp)] with [Ru-3{mu(3)-HC2C=C[W(CO)(
3)(cp)]}(mu-CO)(CO)(9)] (cp=eta-C5H5) afforded an unusual WRu3 cluster
bearing a ligand formed by dimerisation of the diynyl ligand with inc
orporation of two molecules of CO, as shown by a crystal-structure det
ermination.
