摘要：

A combination of two bridged bis(2-pyridylmethyl)amine-type ligands offered efficient separation of lanthanoid tris(beta-diketonates) complexes. The employed ligands bridged two lanthanoid tris(beta-diketonates) to form crystalline ternary complexes. Since the complexes containing larger lanthanoid centers were preferentially precipitated, the bridging ligands selectively recognized the lanthanoid tris(beta-diketonates) in the crystallization process, and offered an efficient separation method.
