The complexes Ru3(μ3-C6H3R){μ-P(C6H4R-3)2}2(CO)6{Au2(PPh3)2} (R = H (2), Me), Ru3(μ3-PPhCH2PPh(C6H4-2)}(CO)8-{Au2(PR3)2} (R = Ph, OMe (5)), Ru3(μ3-NPh)n(CO)10-n{Au2(PPh3)2} (n = 1 (6), 2) and Ru3(μ3-S)2(CO)8{Au2(PPh3)2} have been obtained from reactions between [O{Au(PR3)}3]+ (R = Ph, OMe) and the 'parent' Ru3 clusters; X-ray structural studies of 2, 5 and 6 show that a CO group has been replaced by an Au2(PR3)2 fragment. In contrast, the two Au(PPh3) groups bridge opposite Ru-Ru bonds in Ru6C(μ-CO)2(CO)14{Au(PPh3)}2 (9; X-ray structure). The known complexes Os3(CO)11{Au2(PPh3)2}, and Os3H2-n(CO)10-{Au(PPh3)}n (n = 1, 2) were obtained from Os3(CO)12 and Os3H2(CO)10 respectively.
