“…The average Cu···O distance is quite similar (1.86 AE 0.01 ) to the Cu À O bond lengths for copper dioxygen complexes characterized by X-ray crystallography. [4,6] The Cu···Cu internuclear distances for the oxygenated and oxygen-free xerogels (d CuÀCu = 4.0 and 3.9 respectively) are significantly longer than the Cu···Cu distances in side-on peroxodicopper complexes, but rather shorter when compared to metal-metal distances for end-on [Cu 2 (m-h 1 :…”

“…Insights into the dioxygen adduct formed in the oxygenated xerogel can be obtained from the solution chemistry of copper(i) complexes [5,7,8] or from a systematic review of X-ray crystal structures for Cu À dioxygen complexes. [4,6,75] The oxygenation of Cu I complexes can generate three types of 2:1 Cu/O 2 species: an end-on m-…”

“…Metal-superoxo species are almost always proposed to be formed in the initial dioxygen binding step to the reduced metal center in the oxygen activation mechanisms of metalloenzymes (1)(2)(3)(4)(5). Such species have been found in the reactions of O 2 with heme proteins and models (6,7) as well as with one copper enzyme (8) and several synthetic copper and nickel complexes (9)(10)(11)(12)(13)(14)(15)(16).…”

“…T he first step in the oxygen activation mechanisms of metalloenzymes is typically the binding of dioxygen, resulting in electron transfer from metal to O 2 to form a metal-superoxo species (1)(2)(3)(4)(5). This conversion is best exemplified by heme proteins and synthetic iron porphyrin complexes where there is strong crystallographic and spectroscopic evidence for an Fe III -( 1 -O 2 •Ϫ ) formulation (6,7).…”
