| Abstract: The dissociation constants of N-(para-substituted phenyl) iminodiacetic acid (p-RPhID A, R= Cl, H, CH3, CH3O) and N-(ortho-substituted phenyl) iminodiacetic acid (o-RPhlDA) and the formation constants of binary complex compounds of Cu(Ⅱ)-o-RPhIDA, Cu(Ⅱ)-p-RPhIDA, Co(Ⅱ)-p-RPhIDA, Ni(Ⅱ)-p-RPhIDA and Zn(Ⅱ)-p-RPhIDA were determined by pH method in the presence 0.1mol·dm-3KNO3 at 25℃ . It has been found that linear free energy relationships not only exist between stability of these binary complex compounds and base strength of ligand, but also exist between logβ and σ'(=pK2-pK2).The deviation of Cu(Ⅱ)-o-CH3PhIDA from linearity may be ascribed to steric effect of methyl group at ortho position. |
