complex 2 was oxygenated at 25°C to the extent of a 1:1 molar ratio of dioxygen to complex and a copper(I)-dioxygen complex 3 was spectroscopically indicated as an initial species which degraded to a copper(II) complex, 4, of 1. A dinuclearcopper(II) complex 5 was formed by the reaction of 1 with two equivalents of Cu(ClO4)2·7H2O. The X-band EPR spectra of both 4 and 5 are characterized by axial signals
