| Abstract: | The title compound can be prepared in good yield by heating either Ru4(μ-H)4(CO)12] or Au2Ru4(μ3-H)2(CO)12(PPh3)2] with AuMe(PPh3)] in toluene. The related compound Au3Ru4(μ3-H)(μ-dppm)(CO)12(PPh3)] has also been prepared. Both trigoldtetraruthenium clusters undergo dynamic behaviour in solution, involving intramolecular rearrangement of the metal core, as revealed by variable temperature NMR studies. The crystal structure of Au3Ru4(μ3-H)(CO)12(PPh3)3] has been established by an X-ray diffraction study. The metal atom core comprises a trigonal bipyramidal AuRu4 unit with two AuRu2 faces capped by gold atoms. |
