研究了不同硫代银酸盐AgSR （R = Mes（甲酰基）、Nph（萘酰基）、Cy（环己基））与双齿膦的一系列反应，得到了一系列新化合物，并用x射线单晶衍射对其进行了表征。根据硫化物和磷化物的性质，产物的固态结构从离散的络合物或团簇到三维配位网络各不相同。甲酰基有利于形成三核单元，然后通过磷化基团连接成一个，例如[Ag3(SMes)3(dpph)2](5)，两个，例如[Ag3(SMes)3(dpppt)2](4)，或三个维度[Ag3(SMes)3(dppb)2](3)。与萘基和环己基形成的团簇要么与配体球体中的一些磷烷分离，如[Ag12(SCy)12(dpppt)2](13)，要么另外由磷烷连接形成一维链，如[Ag12(SCy)12(dppo)]（17）。
A series of reactions of different silver thiolates, AgSR (R = Mes (mesityl), Nph (naphthyl), Cy (cyclohexyl)), with bidentate phosphanes was performed yielding a bunch of new compounds, which were characterized by single crystal X-ray diffraction.Depending on the nature of the thiolate and the phosphane the solid state structure of the products varies from discrete complexes or clusters to a 3-dimensional coordination network. The mesityl group favors the formation of trinuclear units which are then linked in one, e.g. [Ag3(SMes)3(dpph)2] (5), two, e. g. [Ag3(SMes)3(dpppt)2] (4), or three dimensions [Ag3(SMes)3(dppb)2] (3), via the phosphanes. With naphthyl and cyclohexyl groups mostly clusters are formed which are either isolated with some phosphanes in their ligand sphere, e.g. [Ag12(SCy)12(dpppt)2] (13), or additionally linked by the phosphanes to form 1-dimensional chains, e.g. [Ag12(SCy)12(dppo)] (17).
