Representative work: Selectivity for An(iii) vs. Ln(iii) binding and extraction using dipicolinamide analogs containing the C[double bond, length as m-dash]O vs. C[double bond, length as m-dash]S groups was investigated in solution and the gas-phase, and by DFT calculations. The results show higher selectivity for complex formation and extraction for Am(iii) vs. Eu(iii) for the softer dithioamide vs. the diamide ligand, while in CH3CN the diamide binds more strongly than the thioamide to several Ln(iii), forming 1 : 1 complexes Abstract [M(EtBTP) 3 ][BPh 4 ] 3 ⋅ 3 CH 3 CN (M=Nd, Am; EtBTP=2,6‐bis(5,6‐diethyl‐1,2,4‐triazin‐3‐yl)pyridine) have been synthesized from reactions of MCl 3 ⋅ n H 2 O with EtBTP in acetonitrile followed by anion metathesis. Structural analysis reveals that these compounds contain M 3+ cations bound by tridentate EtBTP ligands to create a tricapped trigonal prismatic geometry around the metal centers. Collection of high‐resolution, single‐crystal X‐ray diffraction data also allowed reduction in bond lengths esd's, such that a slight contraction of Δ=0.0158(18) Å in the Am−N versus Nd−N bond lengths was observed, even though these cations ostensibly have matching ionic radii.
