The influence of bubbling oxygen into solutions containing cobalt(II) and thiosemicarbazide was studied by spectrophotometry. Several solvents were used: ethylacetate, 1-propanol, ethanol, propylencarbonate, dimethylacetamide and water. The results obtained suggest that the main effect is due to the free ligand oxidation, and that the cobalt(II) probably coordinates O2 molecules during complex formation. The oxidation to cobalt(III) seems to occur only in water, probably because of high donicity
