The reduction of (nBu3P)AgCl with LiBH(sBu)3 in toluene gives the metalloid silver cluster Ag64(PnBu3)16Cl6 (1 ) as dark red, temperature‐ and light‐sensitive single crystals in high yield. 1 is the largest structurally characterized metalloid silver cluster exhibiting chlorine and phosphine substituents only. The silver atoms in 1 show an overall brick‐shape arrangement, where structural resemblance to the close‐packed fcc and hcp structures is realized. Within 1 a 58 electron closed shell system is present. The light sensitivity renders 1 as a model compound for the primary seeds of the photo process, whereby this sensitivity, together with the high‐yield synthesis show that 1 is a perfect starting compound for further investigations like silver‐plating processes.

高度不稳定的类金属簇 Ag64 (Pn Bu3 )16 Cl6 的合成和表征。



( n Bu 3 P)AgCl 在甲苯中用 LiBH( s Bu) 3还原得到准金属银簇 Ag 64 (P n Bu 3 ) 16 Cl 6 ( 1 ) ,为深红色、对温度和光敏感的单晶在高产中。 1是结构特征最大的类金属银簇,仅显示出氯和膦取代基。图1中的银原子呈现出整体砖形排列,其结构与密排 fcc 和 hcp 结构相似。在1内存在 58 个电子的闭壳系统。光敏感性使1成为光过程主要种子的模型化合物,这种敏感性与高产率合成一起表明1是进一步研究(如镀银过程)的完美起始化合物。
