Dedicated to Professor Achim M¸ller on the occasion of his 65th birthday Many investigations towards synthesis and structural characterization of large metal-rich clusters have been reported over the last few years. Particularly noteworthy are the oxometallates of molybdenum described by M¸ller et al.; only recently Na 48 [H x Mo 368 O 1032 (H 2 O) 240 (SO 4 ) 48 ]¥n 1000 H 2 O (x % 16; n % 1000), the largest known derivative of a heteropolyacid was structurally characterized. [1] Other examples of large cluster complexes are [Pd 145 (CO) x (PEt 3 ) 30 ] (x % 60) made by Dahl et al. [2] and [Ga 84 {N(SiMe 3 ) 2 } 20 Li 6 Br 2 (thf) 20 ] reported by Schnˆckel and Schnepf. [3] The synthesis of the larger Ag±S cluster complexes [Ag 14 S(SPh) 12 (PPh 3 ) 8 ] [4] and [HNEt 3 ] 4 -[Ag 50 S 7 (SC 6 H 4 tBu) 40 ] [5] was recently achieved by Jin et al.Over the last few years one of our major fields of interest was the synthesis of transition-metal clusters containing S, Se, Te, P, As, and Sb as bridging ligands, for example, copperchalcogenide clusters stabilized by tertiary phosphane ligands. [6] Reactions of transition-metal salts with Group 16 silyl derivatives E(SiMe 3 ) 2 or RESiMe 3 (R ¼ alkyl-or aryl-; E ¼ S, Se, Te) allows access to these clusters. [7] Addition of tertiary phosphanes to these reactions prevents the formation of the thermodynamically stable binary phase. [8] Compounds obtained by this route include: [Cu 146 Se 73 -(PPh 3 ) 30 ], [9] [Ag 172 Se 40 (SenBu) 92 (dppp) 4 ] [10] [Ag 38 Te 13 (TetBu) 12 (dppe) 6 ] (dppe ¼ bis(1,2-diphenylphosphanyl)ethane), [11] [Au 18 Se 8 -(dppe) 6 ]Cl 2 [12] , and [Zn 16 Te 13 (TePh) 6 (tmeda) 5 ] [13] (tmeda ¼ tetramethylethylenediamine). Herein we report the synthesis of the Ag±S clusters 1, 2, and 3 containing 120 and 282 heavy atoms, respectively, in the cluster core. ½Ag 70 S 16 ðSPhÞ 34 ðPhCO 2 Þ 4 ðtriphosÞ 4 1 ½Ag 188 S 94 ðPnPr 3 Þ 30 2 ½Ag 188 S 94 ðPnBu 3 Þ 30 3The reaction of a suspension of silver benzoate and triphos [1,1,1-tris{(diphenylphosphanyl)methyl}ethane] with a mixture of S(Ph)SiMe 3 and S(SiMe 3 ) 2 (2:1) at À20 8C in diglyme produces a deep red solution from which small red needles of 1 [Eq. (1)], can be isolated.Reaction of S(SiMe 3 ) 2 with silver trifluoroacetate and PnPr 3 at À40 8C in diglyme initially produces a red solution. After a few hours stirring, the reaction is allowed to warm up to room temperature. The solution becomes dark and black crystals of 2 are formed [Eq. (2)]. Employment of PnBu 3 in an analogous reaction produces black crystals of 3 [Eq. (2)]. Depending on the reaction conditions, 2 is often produced together with black amorphous Ag 2 S. Attempts to recrystallize 2 and 3 from THF or CH 2 Cl 2 failed and produced Ag 2 S as the only isolatable material. The different colors of 1 and 2 (red and black) arise from quantum size effect, which result from the dependency of the band gap on particle size.
