本文介绍了计算络合物稳定常数的八种方法,它们是: 1.lgK_1=Az~2/r+Bx_±+C. 2.两相似金属离子与一系列配位体络合时,lgK_1间一的线性关系。 3.两相似配位体与一系列金属离子络合时,lgK_1间的线性关系。 4.一系列相似配位体与同一金属离子络合时,lgK_1与∑pK_a间的线性关系。 5.一系列相近z~2/r的金属离子与同一配位体络合时lgK_1与x_±间的线性关系。 6.一系列相近x的金属离子与同一配位体络合时lgK_1与z~2/r间的线性关系。 7.金属离子随z~2/r和x而变化的络合次序。 8.∑pK_a较大的配位体与z~2/r较大的金属离子匹配,电负性较小的配位体与电负性大的金属离子匹配。
In this paper, eight methods to calculate the stability constants of complexes are introduced: 1.lgK_1 = Az ~ 2 / r + Bx_ ± + C. 2. When two similar metal ions are complexed with a series of ligands, A linear relationship. The linear relationship between two similar ligands and a series of metal ions, lgK_1. 4. A series of similar ligand complexes with the same metal, lgK_1 and ΣpK_a linear relationship between. 5. A series of similar z ~ 2 / r metal ions with the same ligand complexes lgK_1 and x_ ± linear relationship between. 6. A series of similar x metal ions with the same ligand complexes lgK_1 and z ~ 2 / r between the linear relationship. 7. Metal ions with z ~ 2 / r and x changes in the order of the complex. 8.ΣpK_a Larger ligands and z ~ 2 / r larger metal ions match, the lesser electronegativity ligands and electronegativity of large metal ions match.
