【摘要】 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。更多还原

【Abstract】 4,5-bis(cyanoethylsulfanyl)-1,3-dithiol-2-thione(bcdt)(1) and its Ag(Ⅰ) coordination polymer [Ag4(bcdt)4(CF3SO3)2]·(CF3SO3)2·acetone(2)have been synthesized using CS2,DMF,Na,3-bromopropionitrile and AgCF3SO3.The single crystals of the title compounds were obtained by a solvent diffusion method.The ligand and its Ag(I) complex were characterized by elemental analysis,FT-IR and X-ray single crystal diffraction.X-ray single crystal analysis reveals that the S…S contacts in the ligand 1 lead to a 1-D wavy chain,while complex 2 exhibits a novel 3-D open coordination network in which intra-molecular face-to-face and side-by-side S…S contacts exist.The ligand 1 is an insulator at room temperature,however complex 2 exhibits a semiconducting behavior with a σRT value of 6.46×10-8S·cm-1 at room temperature.更多还原
