structurally related flexible heterocyclic thioethers involving thiadiazole, 2,2′-[methylenebis(thio)]bis[1,3,4-thiadiazole] ( L 1 ), 2,2′-[1,2-ethanediyl bis(thio)]bis[1,3,4-thiadiazole] ( L 2 ) and 2,2′-[1,3-propanediylbis(thio)]bis[1,3,4-thiadiazole] ( L 3 ), and three new silver nitrate complexes of these ligands, [Ag L 1 (NO 3 )] 1 , [Ag L 2 ](NO 3 ) 2 2 , and [Ag L 3 (NO 3 )] 3 , have been synthesized
摘要 在此背景下,三种结构相关的柔性杂环硫醚涉及噻二唑、2,2'-[亚甲基双(硫)]双[1,3,4-噻二唑] (L 1 )、2,2'-[1,2-乙二基双(硫代)]双[1,3,4-噻二唑](L 2 )和2,2'-[1,3-丙二基双(硫代)]双[1,3,4-噻二唑](L 3 ) ,以及这些配体的三种新硝酸银配合物,[Ag L 1 (NO 3 )] 1 、[Ag L 2 ](NO 3 ) 2 2 和 [Ag L 3 (NO 3 )] 3 ,已被合成并表征。所有六种新结构均通过单晶 X 射线衍射分析确定。配合物 1-3 分别表现出无限的三维结构、一维锯齿链结构和准二维结构。在三种配合物的晶体结构中,观察到了多种Ag I的配位模式,可能是由于连接单元链长的变化。
