合成和表征了含有硫醚基团的吡啶烷基酰胺配体2-(甲硫基)-N-[2-(2-吡啶)甲基]乙酰胺(HL1)和2-(甲硫基)-N-[2-(2-吡啶)乙基]乙酰胺(HL2)及其3个铜的配合物,{[Cu(L1)(CH3OH)](OTf)}n(1)(Otf=三氟甲磺酸根),{[Cu(L2)(OTf)]·CH3OH}n(2)和[Cu(HL2)(CH3OH)Cl](3),并通过X-射线单晶衍射分析确定了其晶体结构。配合物1和2均为含有铜的一维配位聚合物,而配合物3为单核铜配合物。分析了配合物中铜离子的配位特点及可能的形成原因。 Synthesis and characterization of thioether group-containing pyridyl alkylamide ligands 2- (methylthio) -N- [2- (2-pyridyl) methyl] acetamide (HL1) and 2- (methylthio) {[Cu (L1) (CH3OH)] (OTf)} n (1) (Otf = tris (2-pyridyl) ethyl] acetamide (HL2) and its three copper complexes Fluoromethanesulfonate), [Cu (L2) (OTf)] .CH3OH} n (2) and [Cu (HL2) (CH3OH) Cl] (3) were synthesized and characterized by X-ray single crystal diffraction analysis Crystal structure. Complex 1 and 2 are all copper-containing one-dimensional coordination polymers, while complex 3 is a mononuclear copper complex. The coordination characteristics of copper ions in the complex and possible reasons for their formation were analyzed.
