ملخص

The clusters [H₂Os₄M(CO)₁₂η ⁶-C₆H₆)] (M=Os, Ru) may be deprotonated to generate anions [Os₄M(CO)₁₂(η⁶-C ₆H₆)]^2- which react with [M′η ⁶-C₆H₅R) (MeCN)₃] ²⁺(M′=Os, Ru; R=H, Me) to give the bicapped tetrahedral clusters [Os₄(CO)₁₂MM′(η⁶-C ₆H₅R)₂]. Whereas [Os₄(CO) ₁₂M₂η⁶-C₆H₆) ₂] (M=Os, Ru) have one M(η⁶-C₆H ₆) unit in a site connected to three other metals, {3}, and one in a site connected to four other metals, {4}, [Os₄(CO) ₁₂OsRu(η⁶-C₆H₆)₂] has the Ru(η⁶-C₆H₆) unit in the {3} site irrespective of whether the Os or Ru anion is capped. Coupling of these anions with Au₂dppm yields [Os₄M(CO)₁₂(η ⁶-C₆H₆)(Au₂dppm)] (M=Os, Ru), which have the arene ligand in the axial site of a trigonal bipyramid and the digold unit capping two faces. Reduction of [H₂Os₅(CO) ₁₅] with K/Ph₂CO and coupling with [Ru(η⁵- C₅H₅)(MeCN)₃]²⁺yields the monoanion [Os₅(CO)₁₅Ru(η⁵-C₅H ₅)]^- which reacts with [AuPPh₃]⁺ generating [Os₅(CO)₁₅Ru(η⁵-C ₅H₅)(AuPPh₃)] with the "Ru(C ₅H₅)" unit in the terminal {3} site.
