The epr spectra have been observed for a series of molecular oxygen adducts prepared from Co(acacen) [acacen = (CH3—C(O-)=CHC(CH3)=NCH2-)2]. These reversibly formed adducts, which in general contain an additional base, are unambiguously shown to be monomeric in both fluid and frozen solution. They are further shown to be best characterized as superoxo (O2-) adducts of Co(III). Suggestion is also made as to the probable geometry of these complexes.
