Three copper complexes of nitrogen-sulfur donor ligands, [CuBr₂(L1)] (1), [CuCl₂(L2)₂] (2) and [Cu₂I₂(L3)]n (3) (L1 = bis(2-cyclohexylsulfanylethyl)amine, L2 = 2-(benzylsulfanylmethyl)pyridine and L3 = 2-(4-pyridylsulfanylmethyl)pyridine), have been synthesized and characterized by single-crystal X-ray diffraction (XRD), powder XRD and TGA analysis. Complexes 1 and 2 are mononuclear Cu(II) complexes and are EPR active with distorted square-pyramidal and octahedral geometry, respectively. Complex 3 is a two-dimensional tetrahedral Cu(I) coordination polymer with 16- and 20-membered metallocycles. These complexes show good catalytic activities for one-pot azide-alkyne cycloaddition reactions in CH₃OH-H₂O.
三种氮硫供体配体的铜配合物，[CuBr₂(L1)]（1）、[CuCl₂(L2)₂]（2）和[Cu₂I₂(L3)]n（3）（L1=双（2-环己基硫代乙基）胺，L2=2-（苄基硫代甲基）吡啶，L3=2-（4-吡啶基硫代甲基）吡啶），已经通过单晶 X 射线衍射（XRD）、粉末 XRD 和 TGA 分析进行了合成和表征。配合物 1 和 2 是单核 Cu(II)配合物，具有分别为扭曲的四方锥和八面体几何形状的 EPR 活性。配合物 3 是一种二维的四面体型 Cu(I)配位聚合物，具有 16 元和 20 元金属环。这些配合物在 CH₃OH-H₂O 中对一锅法叠氮-炔环加成反应具有良好的催化活性。
