The X-raystructure of a 1:1 Cu/O(2) adductrevealed side-on (eta(2)) O(2) coordination. Density functional calculations corroborated the structure, indicated a significant contribution of a Cu(III)-(O(2)(2-)) resonance form, and provided insights into the key bonding interactions. Reaction of a 1:1adduct supported by a slightly different beta-diketiminate ligand with Cu(I) reagents resulted in the
