The copper atom reacts with dioxygen in solid argon to form a mononuclear copper dioxygen complex Cu(eta(2)-O(2))(eta(1)-O(2))(2) bearing both side-on and end-on bonded O(2) ligands. The complex is characterized as being a trisuperoxide species with the copper center in its unusual +3 oxidation state. The Cu(III) trisuperoxide complex loses an end-on bonded superoxo ligand in forming the copper bisdioxygen complex under infrared irradiation.
铜原子在固态氩中与双氧反应形成单核铜双氧配合物Cu(η(2)-O(2))(η(1)-O(2))(2)，该配合物同时含有侧端和末端键合的O(2)配体。该配合物被表征为一种三超氧物种，铜中心处于其不寻常的 +3氧化态。在红外辐射下，Cu(III)三超氧配合物在形成铜双双氧配合物时会失去一个末端键合的超氧配体。
