自从本世纪初布德兰德(Bodlader)等首先测定了铜、银络合物的稳定常数起,迄今已有60余年的历史。目前已经积累了相当数量的各种络合物的稳定常数。但对络合物的分步稳定常数间关系的研究,或对络合物分步稳定常数随配位数增加而改变规律的研究为数不多。雅齐米尔斯基曾指出,络合物分步稳定常数间的关系是一个相当重要的问题。可以说 Since the beginning of this century, Bodlader and others first determined the stability constants of copper and silver complexes, and has been more than 60 years old. A large number of stable constants of various complexes have been accumulated so far. However, few studies have been done on the relationship between the step-stable constants of complexes and on the variation of the step-stable constants of complexes with increasing coordination number. Yazimi Milsky has pointed out that the relationship between the step-by-step stability constants of complexes is a very important issue. It can be said
