Step-wise formation constants were determined for the rare earths (including yttrium) with piperdine-2,6-dicarboxylic acid. The measurements were made in aqueous solutions of ionic strength mu = 0.1 (KNO/sub 3/) and a temperature of 25DEC.The data were interpreted in terms of 1 : 1 and 2:1 chelates. Trends in the values of log K/sub 1/ and log K/sub 2/ are discussed and compared with similar values for other ligands which contain thc same basic chelating structure. It is shown that the size of the metal ion is an important factor in determining the magnitude of the formation constants of piperidine-2,6- dicarboxylic acid chelates in much the same way as in the chelates of dipicolinic acid.
