Cleavage of the gold-methyl bond occurred in the reaction of [AuMe(PPh3)] with [H2Os3(CO)i0] (2/5), where methane elimination was accompanied by formation of the mixed-metal cluster [ H AuOs(CO)10(PPh3)]. [Pg.72]

Melnik and Parish (10) correlated 197Au Mossbauer and X-ray structural data for gold clusters in 1986, and Salter (11) has recently published a review of the stereochemical nonrigidity exhibited in solution by the metal skeletons of some mixed-metal clusters containing copper, silver, and gold. [Pg.250]

It is possible to synthesize mixed-metal clusters containing Au(PR3) fragments by treating neutral as well as anionic precursors with either [Au(PR3)]+ or a compound that acts as a source of this cation. In many cases, a [Au(PR3)]+ unit is simply added to the cluster precursor to afford a cationic heteronuclear gold cluster (e.g., 59,62-66). Equation (27)... [Pg.256]

A homonuclear gold cluster has been used as a precursor to a heteronuclear species in which two gold atoms are bonded to Co(CO)4 fragments [Eq. (55)] (90). Treatment of the cluster salt K[Co3Fe(CO)12] with [Bu"N][AuI2] also affords a mixed-metal cluster containing a Au Co-(CO)4 unit [Eq. (56)] (91). [Pg.259]

Another area of major interest in the field is that of mixed metal cluster systems. Hieber very early in the study of metal carbonyl chemistry was able to prepare mercury complexes of the type Fe(CO)4(HgCl)2. The related gold ° compounds were prepared in the 1960s by reaction of phosphine gold halides with carbonyl anions. [Pg.1770]

Multidentate phosphine-gold(i) fragments can be used to build up high-nuclearity mixed-metal clusters. The interaction of [(triphos)(AuCl)3] (triphos= l,l,l-tris(diphenylphosphinomethyl)ethane) with the iron anions [Fe2(//-L)(C0)7] (L = PPh2, HC=CHPh, PhC=GHPh, CO) gave the corresponding mixed-metal clusters [ Fe2(jLt-L)(CO)7Au 3(triphos)], as shown in Scheme... [Pg.344]
