Facile O 2 release from an oxyhemocyanin model has been achieved for the first time, with the new room‐temperature‐stable μ‐η 2 :η 2 ‐peroxodicopper complex [Cu 2 O 2 (L2)] 2+ ( 1 ). X‐ray structural and spectroscopic studies on 1 show that elongation of the CuO bonds, induced by the bridgehead methyl groups of L2, is responsible for the ease of O 2 release. CO/O 2 binding by 1 , monitored by UV/Vis spectroscopy (see picture), is completely reversible.
