Abstract: In this study, we investigated the complexation equilibrium and stability of proton transfer systems, binary and ternary complexes of pyridine-26-dithiocarboxclic Acid or dipicolonic acid (pydc) and nicotine amide (na) with Ce3 + by potentiometric method and the results Compared with their spectrum information or X-ray crystal structures in solid state. The ion in an aqueous solution was investigated by potentiometric pH titration. The stoichiometry of the most complex species in the solution was found to be similar to the crystalline complexes.
