Charge distribution in dioxygen complexes of cobalt(III). The crystal structure and absolute configuration of (+)546-Δ-cis-β-[{2,13-dimethyl-6,9-diphenyl-2,6,9,13-tetraarsatetradecane}(dioxygen)cobalt(III)] perchlorate

“…Un des cycles a six membres existe sous une conformation chaise; I'autre est desordonne et se produit avec une probabiliti egale de conformation chaise et de bateau croise. Le chelate de cycle a cinq membres a une conformation gauche Introduction Dioxygen complexes of group VIII transition metals have been the subject of several recent reviews (1)(2)(3)(4). Two different modes of attachment of the 0, ligand to the metal atom have been demonstrated.…”

How useful are vibrational frequencies of isotopomeric O2 fragments for assessing local symmetry? Some simple systems and the vexing case of a galactose oxidase model

“…Typical values for O-O stretching frequencies of 1,075-1,200 cm À1 for superoxo ligands and 790-930 cm À1 for peroxo ligands are well established [15,16] and make such an approach practical. For example, a m( 16 O- 16 O) frequency of 1,122 cm À1 was used to identify a 1:1 Cu-O 2 species supported by a tris(2-dimethylaminoethyl)amine ligand as a superoxo complex (1, Structure 1) [17].…”

Hot-atom mechanism in photodesorption of molecular oxygen from a stepped platinum (113) surface

“…These values are not unreasonable because the admolecule seems to be located further from the surface, 46 and oxygen adatoms are 0.85 Å above the platinum plane. 47 This consideration suggests that hot-atoms are moved toward the surface as well as along the trough, as expected due to the attractive force needed to yield a strong oxygen-metal bond ͑about 3.7 eV͒.…”
