presence of potassium carbonate. Complexes of these compounds (L) with CoCl2 were synthesized. In all cases, the complexes L(CoCl2)2 were formed regardless of the ratio of L and inorganic salt introduced into the reaction. According to electronic spectroscopic data, the cobalt atom in the complexes has a tetrahedral coordination environment. The synthesized ligands and complexes were electrochemically studied
