Some unexpected “structure–extraction properties” patterns were found for new family of 1,10-phenanthroline-2,9-diamide derived ligands.

A new phosphine oxide ligand demonstrates high selectivity for the Am–Cm pair with SF = 2.9–3.5 and the Am–Eu pair with SF = 7.3–8.5 in the range of 0.1–3 M nitric acid.

In this work we report on new examples of phenanthrolindiamides containing asymmetric centers in amide substituents. The synthesized ligands are expected to have complex thermodynamic behavior. Their structure was unambiguously...
