Seven new cobalt(II) complexes with a tetradentate Schiff base and their three oxygen adducts were synthesized. The adducts were stable at room temperature for several weeks. The isolated oxygen adducts showed intense new bands in the 1130–1150 cm<SUP>−1</SUP> range characteristic of superoxide-like 1:1 oxygenated metal complexes. The ESR spectra of the adducts showed eight-lined, hyperfine structures with a very small splitting (10–20 G) at 77 K. The adducts obtained were identified as monomeric 1:1 oxygen species, two complexes of which showed a reversible oxygenation in a 1,2-dichloroethane solution at 6 °C.
