Abstract

The reaction of the dianion [Os₄H₂(CO)₁₁]^2- with two equivalents of Au₂(DPPM)Cl₂ (DPPM = Ph₂PCH₂PPh₂), in the presence of Tl[PF₆], affords a digold species which upon treatment with NEt₃ gives the neutral cluster [Os₄H₂(CO)₁₁{Au₂(DPPM)}₂]. This cluster has been characterised by ¹H and ³¹P NMR spectroscopy, mass spectrometry and X-ray crystallography. The metal core consists of an Os₄ tetrahedron, one face of which is capped by three Au atoms while the fourth Au atom caps an OsAu₂ face.
