摘要/Abstract

摘要： 用pH电位法及温度系数法证实了混型配合物α-氨基酸-邻菲哕啉-铜(Ⅱ)中的线性自由能、线性焓及线性熵关系。

Abstract: The stability constants of ternary mixed ligand coordination compounds formed from some amino-acids (serine, valine, alanine and α-amino-isobutyric) and 1,10-phenanthroline with Cu(Ⅱ) were determined by pH-meterically at 25±0.1℃, 35±0.1℃ and 45±0.1℃ in the presence of 0.16M KNO₃Linear relationships not only exist between the stability of ternary mixed ligand coordination compound and the base strength of ligands but also exist between the formation enthalpy of coordination compounds and the protonalion enthalpy of the ligands and between the formation entropy of coordination compounds and the protonation entropy of the ligands as well.
