The thermodynamic parameters of formation of the 1:1 complex between samarium cation and lutidinate have been measured using potentiometric and calorimetric techniques in aqueous solution of 0.50M (NaClO₄) ionic strength at 25℃. The results have been compared with those for the other analogous heterocyclic carboxylate ligands. From the comparison of the thermodynamic data, it was found that the lutidinate ligand was coordinated to the samarium cation by forming the chelate through the ring nitrogen atom at position 1 and the carboxylate group at position 2 of the pyridine ring.
