Abstract
The synthesis and crystal structures of the clusters M3(AuPPh3)(C≡CFc)(CO)9 (M=Ru,3a; or M=Os,3b) are described. Compound3a was synthesized by deprotonation of Ru3H(C≡CFc)(CO)9 under the action of KOH/EtOH followed by treatment of the anionic complex [Ru3(C≡CFc)(CO)9]− with chloro(triphenylphosphine)gold. Compound3b was prepared by the reaction of Os3(CO)10(NCMe)2 with FcC≡CAuPPh3, which was synthesized by the reaction of FcC≡CNa with ClAuPPh3. The pentanuclear cluster Ru4(AuPPh3)(C≡CFc)(CO)12 (4a), which was prepared by the reaction of3a with Ru3(CO)12, was characterized by spectral methods.
