Uptake of nitric oxide by cobalt(II) chelates with selected dipeptides was iiwestigated by volumetric and spectrophotometric methods (UV, VIS). The temperaturę was reduced to ~0°C in order to inhibit the autooxidation of Co(II) to Co(III). The stoichiometry of NO addition and the reversibility of the reaction (by re-acidification and re-argonation) were investigated as well. The reaction was reversible in a varying degree depending on the kind of amino acid side groups used. The kinetic stability of the formed NO adducts was followed spectrophotometrically. Present and previous results, concerning fixation of dioxygen in similar systems, arę compared.
