摘　　要：用pH电位滴定法测定了Zn2+,Cu2+,Ni2+和Co2+与氨基酸水杨醛席夫碱及ATP形成的三元配合物的稳定常数,发现logβ111与pk2之间存在很好的线性自由能关系,研究了三元配合物中配体间的疏水相互作用.The stability constants of ternary complexes of N- Salicylideneaminio acid and ATP with Zn^2＋ , Cu^2＋ , Ni^2＋ and Co^2＋ had been determined by pH method. It was found that the linear free energy relationship （LFER） exists nicely between β111 and pK2. The log was used to characterize the stability of ternary complexes related to the stability of parent binary complexes . The hydrophobic interaction between ligands in the ternary complexes was studied.
