Bidentate ligands containing 1,4-disubstituted-1,2,3-triazole units are by far the most studied class of click chelates. Within this subclass of click ligands, the pyridyl-1,2,3-triazole ligands 2-(l-R-lH-l,2,3-triazol-4-yl)pyridine 30 and [2-(4-R-lH-l,2,3-triazol-l-yl)methyl]pyridine 31 have received the most attention.

It is clear that the CuAAC click reaction can be exploited to rapidly synthesize families of functionalized ligand architectures, and this synthetic versatility could lead to many potential applications. However, before the full potential of these click ligands can be realized, an understanding of the coordination properties of 1,4-disubstituted-l,2,3-triazoles is required. In the following sections, we will examine the coordination properties of monodentate, bidentate, tridentate, and polydentate ligands containing 1,4-disubstituted-l,2,3-triazole units.
