Solvent extraction of rare earth elements using a new type of diamide ligand, DODGAA, was performed to investigate the extractability and separability of the ligand for the separation of rare earth elements. Single crystals of the DODGAA complexes with some rare earth metals were also synthesised and structurally determined by single-crystal X-ray diffraction (SC-XRD) to understand the molecular structure of extracted species.

Keywords: Rare earth elements; separation; solvent extraction; structure determination; single-crystal X-ray diffraction
