Selective crystallization of dysprosium complex from neodymium/dysprosium mixture enabled by cooperation of coordination and crystallization.

Designing a molecular-level Ln 3+ separation system remains a challenge for developing next-generation separation methodologies. Herein, we report crystallization-based Nd 3+ /Dy 3+ separation using a tripodal Schiff base ligand. Highly selective crystallization of the Dy 3+ complex was enabled by cooperation between the coordination and crystallization processes.
