Article abstract of DOI:10.1021/om00097a037

Reaction of either the carboxylate-bridged dimers [Ru(CO)2(μ-O2CR)(NCMe)]2 or the polymeric dimers [Ru2(CO)4(μ-O2CR)2]n (R = Me, Et) with 1 equiv (per dimer unit) of the bidentate groups L2 (L2 = R′2PCH2PR′2, R′ = Ph (DPPM), Me (DMPM); L2 = R′SCH2SR′, R′ = Ph, Me) yields the unusual Ru(I) polymers [Ru2(CO)4(μ-O2CR)2(L 2)]n, in which two metals are bridged by two carboxylate groups and these binuclear units are linked by diphosphine or dithioether ligands. Reaction with 2 equiv of the diphosphine Ph2PCH2PPh2 in THF yields the neutral disubstituted dimer [Ru2(CO)4(μ-O2CMe)2(η 1-DPPM)2], whereas with DPPM or Ph2P(CH2)2PPh2 (DPPE) in alcohols two types of cationic compounds of formula [Ru2(CO)4(μ-O2CMe)(L2) 2]+ (L2 = DPPM, DPPE) are obtained. The X-ray structures of both cationic species have been determined and show that one has the Ru(I) centers bridged by two DPPM and one acetate ligand, whereas the other has two bridging carbonyls and one bridging acetate group, with one DPPE chelating each metal.
