Abstract

The reduction of ( Bu P)AgCl with LiBH( Bu) in toluene gives the metalloid silver cluster Ag (P Bu ) Cl (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.

摘要

在甲苯中用LiBH(Bu)还原(Bu P)AgCl可高产率地得到类金属银簇合物Ag (P Bu ) Cl (1)，呈深红色，对温度和光敏感的单晶。1是仅表现出氯和膦取代基的最大的经结构表征的类金属银簇合物。1中的银原子呈现出整体的砖形排列，与密堆积的面心立方和六方密堆积结构存在结构相似性。在1中存在一个58电子的闭壳层体系。光敏感性使1成为光过程初级种子的模型化合物，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理想起始化合物。
