Abstract
The action of CO on the pentanuclear carbido cluster [Ru5C(CO)14(AuPR3)2][PR3= PEt3(2), PMe2Ph (3)](80 atm, 60 °C) affords the tetranuclear carbido cluster [Ru4C(CO)12(AuPR3)2][PR3= PEt3(4) PPh3(5), PMe2Ph (6)], which exhibits a carbide-centred, ‘butterfly’ Ru4C core with both the ‘wing-tip’ and ‘hinge’ Ru atoms bridged by AuPR3 groups; the ‘hinge’ bridging AuPR3 group may be replaced by reaction with I2 or HI to give [Ru4C(CO)12(I)(AuPR3)][PR3= PEt3(7), PPh3(8)] and [Ru4(H)C(CO)12(AuPR3)][PR3= PEt3(9), PPh3(10)], respectively, and the subsequent reaction of (9) and (10) with [BH4]– removes the remaining AuPR3 group, acidification affording the tetraruthenium carbide [Ru4(H)2C(CO)12](11)Keywords
