Recently, we found that the gold oxo complexes [(AuL)[sub 3]O]BF[sub 4] (L = phosphine) are excellent precursors for the high-yield synthesis of gold clusters. We find that smaller phosphine ligands (L = PPh[sub 2]Me, PPhMe[sub 2]) give [(LAu)[sub 10]Au][sup 3+] clusters, while larger phosphine ligands (L = PPh[sub 3], P(p-ClPh)[sub 3]) give [(LAu)[sub 6]][sup 2+] clusters. These results led us to the synthesis of the oxo and hydroxy complexes [(AuL)[sub 3]O]BF[sub 4] and [(AuL)[sub 2]OH]BF[sub 4] with the very bulky phosphine ligand L = P(mesityl)[sub 3] in efforts to synthesize the unknown trinuclear cluster (LAu)[sub 3[sup +]]. In this communication, we report the unexpected isolation and structural characterization of a novel gold cluster (Au[sub 8]L[sub 6])[sup 2+] with an unusual open structure. The high-yield preparation of the gold cluster [(AuL)[sub 4]][sup 2+], a type only recently discovered, is also reported. 16 refs., 1 fig.
