amino acids ser, met and phe, while in the Ni(II)-Hpic-Hthr system only the complexes Ni(pic)L and [Ni(pic)(L) 2 ] − were formed. The equilibrium and formation constants of the resulting ternary complexes have been calculated at I = 1.0 mol.dm −3 of NaCl. The stability of the ternary complexes was quantitatively compared with their corresponding binary complexes in terms of the parameters Δ log 10 K″. The
