Ligands possessing multiple complexation modes are an interesting class of compounds. Here we report that our recently established pincerclickligands (PCLs), prepared by copper-catalyzed cycloaddition of azides to alkynes, exhibit unique versatility in coordination ability. Nitrogens of the triazole-based backbone can actively participate in metal ligation rather than being a spectator backbone.
