摘要：

The complexes [Ru-3(mu-dppm)(PR3)(CO)(9)] (R=Et, Ph, Cy, Pr'} were prepared from [Ru-3(mu-dppm)(CO)(10)] by simple phosphine substitution reactions at room temperature and their structures determined by single crystal X-ray studies. Variations in the Ru-Ru bond adjacent to the phosphine ligand suggest the enhanced reactivity of [Ru-3(mu-dppm)(CO)(10)] over the parent carbonyl [Ru-3(CO)(12)] to be consequent on the inability of [Ru-3(mu-dppm)(CO)(10)] to effectively relieve steric congestion imposed by the presence of the bulky, bidentate dppm ligand.
