ملخص

The clusters [H2Os4M(CO)12η 6-C6H6)] (M=Os, Ru) may be deprotonated to generate anions [Os4M(CO)126-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)126-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.
