我们认为,如金属离子M能与配位体A和B形成二元络合物,那么在配位数允许和不存在空间障碍的情况下,总有三元络合物形成.但由于两种配位体之间的浓度比例调节不当,会造成三元络合物在溶液里的所有组份中占很小的比例,这样,往往给人们一个错觉,即没有三元络合物形成,三元混配络合物在溶液里所有组份中所占的比例达到极大时,两配位体之间的浓度比例是可以通过计算得到的。 设在金属离子M和配位体A和B的溶液体系中,有二元络合物MA,MA_2,…,MA_n;
In our opinion, if the metal ion M can form a binary complex with the ligands A and B, then ternary complexes always form with and without the coordination barrier, but since the two complexes Improperly adjusting the concentration ratio between the ligands results in a small proportion of the ternary complex in all components of the solution, thus often giving the illusion that no ternary complex is formed and that the ternary When the proportion of the mixed complex in all the components in the solution reaches a maximum, the concentration ratio between the two ligands can be calculated. Binary complexes MA, MA_2, ..., MA_n are provided in the solution system of metal ions M and ligands A and B;
