Extraction equilibrium and structural chemistry of rare earths with a nitriloacetic acid diamide-type ligand

We have developed a novel nitriloacetic acid diamide-type ligand, and investigated the extraction behavior of rare-earth metal ions using the ligand. It was found that the ligand provides a remarkably high selectivity for scandium among rare-earth elements. In addition, we clarified crystal structure of the complexes by single-crystal X-ray diffraction. The clear differences in the chemical structures between scandium complexes and lanthanum complexes were demonstrated.
