A nanoscale drum-like hexanuclear silver(I) cluster [Ag(pfbt)(PPh 3)]6 1 (Hpfbt = pentafluorobenzenethiol), which showed the arrays of channels based on its self-assembly in the solid, was obtained by the 1:1 molar-ratio reaction of

The reaction of [Au2Cl2(μ-dppf)] (dppf = 1,1′-bis(diphenylphosphino)ferrocene) with 2 equiv of pentafluorobenzenethiol in the presence of K2CO3 leads to the gold(I) thiolate derivative [Au2(SC6F5)2(μ-dppf)] (1). Complex 1 reacts with [Au(OClO3)(PR3)] in a 1:2 or 1:4 molar ratio to give [Au4(μ3-SC6F5) 2(μ-dppf)(PR3)2](ClO4) 2 (PR3 = PPh3 (2), PPh2Me (3)) or [Au6(μ4-SC6F5) 2-(μ-dppf)(PR3)4](ClO4) 4 (PR3 = PPh3 (4), PPh2Me (5)), in which the thiolate ligands bridge two or three gold atoms, respectively. The treatment of 1 with [Au(C6F5)3OEt2] affords the mixed gold(I)-gold(III) species [Au4-(μ3-SC6F5) 2(C6F5)6(μ-dppf)] (6). Heterometallic derivatives have been obtained by reaction of 1 with copper or mercury salts and are of the type [Au2-Cu(μ3-SC6F5) 2Cl(μ-dppf)(PPh3)] (7), [Au6Cu2(μ3-SC6F5) 6(μ-dppf)3](PF6)2 (8), or [Au2Hg(μ3-SC6F5) 2X2(μ-dppf)] (X = Cl (9), 1 (10)). The reaction of 1 with 1 equiv of AgClO4 gives a precipitate of [Ag(SC6F5)]n and the complex [Au2(μ-SC6F5)(μ-dppf)]ClO4 (11) with the thiolate ligand bridging both gold atoms. By reaction of 11 with the gold(III) derivative [Au(C6F5)2-(OEt2) 2]ClO4 the complex [Au5(C6F5)2(μ3-SC 6F5)2(μ-dppf)2](ClO 4)3 12 can be isolated. The complexes 6 and 11 have been characterized by X-ray diffraction studies.
