Abstract: Treatment of the spiked cluster [Ru4(CO)13(μ-H)2(μ4-PCF 3)] with [Au(PMe3)Cl] in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) results in deprotonation and metal core rearrangement from spiked to butterfly, yielding the heterometallic cluster [Au2Ru4(CO)12(μ4-PCF 3)(PMe3)2] 1. Reaction of the open chain cluster [Ru4(CO)12(μ-H)2(μ3-PCF 3)2] with [Au(PPh3)Cl] under similar conditions gives [Au2Ru4(CO)12(μ3-PCF 3)2(PPh3)2] 2 where the hydrides are simply replaced by AuPPh3 fragments. Clusters 1 and 2 are characterised by spectroscopy and X-ray crystallography. © 1999 Elsevier Science S.A.
