在最近的一篇通讯中指出，一系列内部金属配合物的稳定性顺序基本上是相同的，无论这些金属与双齿螯合分子如水杨醛、甘氨酸或8-羟基喹啉结合。从其他工作者的研究结果中可以发现，在复合阳离子和由四齿螯合分子形成的内部络合物中，也存在同样的顺序。Bjerrum2,4和Carlson， MeReynolds和Verhoek3研究了含有乙二胺的阳离子。随附的表显示了水杨醛和乙二胺配合物的总体稳定性常数，从表中可以明显看出，这两种情况的顺序相似。
IN a recent communication1it was pointed out that the order of stability of a series of internal metal complexes is substantially the same whether the metals are combined with bidentate chelate molecules like salicylaldehyde, glycine or 8-hydroxyquinoline. There is evidence from the results of other workers2,3that the same order is to be found with complex cations and with internal complexes formed with quadridentate chelate molecules. Cations containing ethylenediamine have been studied by Bjerrum2,4and Carlson, MeReynolds and Verhoek3. From the accompanying table, which shows the overall stability constants for salicylaldehyde and ethylenediamine complexes, the similarity of order in the two cases is evident.
