摘要：

The kinetics of O-2 reaction with dinuclear 2a, having linked tris[(2-pyridyl)methyl]-amine (L) moieties, are described. Both Cu/O-2 = 1:1 adducts and a Cu/O-2 = 2:1 mu-peroxo species (2c) form. At typical concentrations, this overall reaction is faster than that observed for the parent mononuclear analogue [(L)Cu-I(RCN)](+) (1a), which forms [{(L)Cu-II}(2)(O-2)](2+) (1c); however, its thermodynamic stability is not enhanced. Relative enthalpic vs entropic contributions are detailed.
