Ligand‐induced perturbation of structure and function of a copper–dioxygen complex is revealed by structural characterization and reactivity studies of the complex shown on the right. In addition to preventing formation of a (μ‐peroxo)dicopper isomer, notable effects arising from the ethylene linker between the capping ligands include discernible puckering of the [Cu 2 (μ‐O) 2 ] 2+ unit, lengthened CuO distances, and slowed intramolecular monooxygenase reactivity compared to planar analogs lacking the tether.
