在一个含有一种金属离子和两种不同配体的M-A-B系统中,除去形成二元络合物MA_n和MB_n之外,会不会还有三元络合物MA_aB_b形成?这是一个有实际意义的问题,需要有一些简便方法去确定。当MA_aB_b有特征光谱,有别于二元络合物时,测定光谱自然是可取的。但大多数情况并不如此。在络合剂是弱酸,它们与金属离子配位结合时,发生质子取代,释放质 In an MAB system containing one metal ion and two different ligands, is there any further ternary complex MA_aB_b formed apart from the formation of the binary complexes MA_n and MB_n? It is a practical matter The problem, there are some simple ways to determine. When MA_aB_b has a characteristic spectrum that is different from the binary complex, it is naturally advisable to measure the spectrum. But in most cases this is not the case. In the complexing agent is a weak acid, they coordinate with the metal ions, proton substitution occurs, the release of quality
