Lanthanide(III) complexes of a highly efficient actinide(III) extracting agent - 2,6-bis(5,6-dipropyl-1,2,4-triazin-3-yl)pyridine

The addition of lanthanide(III) nitrates (Sm-Lu) to the actinide(III) extracting agent - 2,6-bis(5,6-dipropyl-1,2,4-triazin-3-yl)pyridine (L-1) in a 1:1 ratio results in the crystallisation of complexes containing [Ln(L-1)(3)](3+) moieties and a variety of anions.
