Inherently dinuclear iridium(iii) meso architectures accessed by cyclometalation of calix[4]arene-based bis(aryltriazoles)

Conventional cyclometalation of calix[4]arene bis(aryltriazoles) with iridium(iii) chloride hydrate leads to unique meso architectures in which the Ir2Cl2 core is cross-bound by two (C<^>N)(2) ligands, which allows further replacement of the chloride bridges with ancillary ligands while maintaining the dinuclear structures of the complexes having independent or coupled iridium pairs.

Automated summary

Conventional cyclometalation of calix[4]arene bis(aryltriazoles) with iridium(iii) chloride hydrate results in unique meso architectures, where the dinuclear complexes contain independent or coupled iridium pairs which can be further modified by replacing chloride bridges with ancillary ligands.
