由二硫化碳、二甲基甲酰胺(DMF)、金属钠、3-溴丙腈和三氟甲基磺酸银等合成了4,5-二腈基乙硫基-1,3-二硫代环戊烯-2-硫酮(bcdt)(1)及其Ag(Ⅰ)配位聚合物[Ag4(bcdt)4(CF3SO3)2]·(CF3SO3)2·acetone(2),并使用溶剂扩散法得到了它们的单晶.通过元素分析、红外光谱和X射线单晶衍射分析等对配体和配合物的组成和结构进行了表征.X射线单晶衍射分析表明:配体1通过S…S相互作用形成了一维的链状结构;配位聚合物2则借助配位键构建出一个新颖的三维网络结构,分子内存在着广泛的面对面和肩并肩的S…S相互作用.配体1是绝缘体,而配合物2室温电导率σRT=6.46×10-8S·cm-1.
