Abstract

The synthesis of the intracomplex compound (ICC) of cobalt(III) with diethanoamine [Co(DetmHdetm)] was carried out, and the stability of the obtained compounds was investigated in a non-aqueous solvent (dimethylformamide) at different pH values. Using the methods of potentiometric titration and UV-Vis. spectrophotometry, the limits of the pH values of the medium in which ICC remain stable were determined.
