摘要：

The reaction of the dianion [Os4H2(CO)(11)](2-) with two equivalents of Au-2(DPPM)Cl-2 (DPPM = Ph2PCH2PPh2), in the presence of Tl[PF6], affords a digold species which upon treatment with NEt3 gives the neutral cluster [Os4H2(CO)(11){Au-2(DPPM)}(2)]. This cluster has been characterised by H-1 and P-31 NMR spectroscopy, mass spectrometry and X-ray crystallography. The metal core consists of an Os,tetrahedron, one face of which is capped by three Au atoms while the fourth Au atom caps an OsAu2 face. (C) 1997 Elsevier Science S.A.
