摘要
氨基酸水杨醛席夫碱配合物是研究磷酸吡哆醛催化氨基酸酶反应极好的模型体系，而且它们又具有抗菌，抗癌活性，因此，得到了人们的重视［１，２］，但对其配合物的稳定性却研究极少，为此我们合成了氨基酸水杨醛席夫碱配体（记为Ａ配体，缩写为Ｓａｌ：Ａ，Ａ＝Ｇ，甘氨酸...
The stability constants of binary complexes of Zn(Ⅱ) α amino acid and ternary complexes of Zn(Ⅱ) N Salicylideneaminio acid (ligand A) α amino acid(ligand B) at (25±0 1)℃ and in the presence of 0 1 mol·L -1 KNO 3 have been determined by pH method The α amino acid(Aa) used were Glycine(Gly), L Serine(Ser), L Leucine(Leu), L Proline(Pro) and L Phenylalanine(Phe) It was found that the linear free energy relationship (LFER) exists nicely between the following parameter pairs log β 102 and pK B 2, log β 111 and pK B 2, and log β 111 and pK A 2 The ΔlgK 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
