[Ag（dppm）（NO_3）]_2（1）与双（二苯基膦基甲烷）二硫代二氰基亚乙基二氢钾（dppm）在DMF中反应，生成配合物[Ag_4（μ-dppm）_4（μ_4-S_2C =C（CN）_2）_2]（2）。用单晶X射线衍射分析确定了2的晶体结构。2是一个四核配合物，银-银间距为3.376（2）nm，四个银原子通过四个dppm和两个i-mnt配体桥连形成一个扭曲的正方形平面.每个银原子与两个磷原子和两个硫原子配位，形成畸变四面体环境。研究了化合物2的IR、~ 1H和~（31）PNMR光谱性质。
The reaction of [Ag(dppm) (NO3)]2(1) with potassim i-mnt 2,2-dicyano-1,1-ethylenediothiolate; dppm bis (diphenylphosphino)methane) in DMF at room temperature gave rise to the complex [Ag4(μ-dppm)4(μ4-S2C=C(CN)2)2] (2). The crystal structure of 2 has been determined by single crystal X-ray diffraction analysis. 2 is a tetranuclear complex with a silver-silver separation of 3.376(2) Å and the four silver atoms form a distorted square plane bridged by four dppm and two i-mnt ligands. Each silver atom is coordinated by two phosphorus and two sulfur atoms in a distorted tetrahedral environment. The IR,1H and31P NMR spectroscopic properties of 2 have also been investigated.
