摘要

The click-ligands based on 1,2,3-triazole and pyridine unit has been synthesized via Cu(I)-catalyzed alkyne-azide cycloaddition from corresponding organic azides and terminal alkynes. The ligand structure was characterized by NMR, IR and elemental analysis as well as single crystal diffractions. The single crystal structure of the complexes from two different ligands coordinating to Cu(II) and Co(II) ions indicated that the N(2) atom in 1,2,3-triazole unit can act as an efficient donor to metals through the rational molecular design.
