摘要：
The composition and stability constants of complexes formed by copper(II) with oxoglutarate have been investigated in aqueous medium. The complexes with metal to ligand ratio as 1:1, 1:2, 1:3 have been reported at pH 6.8. The values of formation constants log beta(1) = 2.66, log beta(2) = 3.34, log beta(3) = 4.37 at 303 K and log beta(1) = 2.14, log beta(2) = 3.32, log beta(3) = 3.39 at 313 K were calculated by DeFord and Hume method. The mathematical Mihailov method was also used. Thermodynamic functions and kinetic parameters have been determined.
