Addition of 2,6-bis(5,6-dialkyl-1,2,4-triazin-3-yl)pyridines (btp) to UI 3 and CeI 3 in anhydrous pyridine gave the 1∶3 complexes [M(btp) 3 ]I 3 , the terdentate nitrogen ligand being completely selective for U III over Ce III , as shown by 1 H NMR competition experiments; crystal structures of analogous btp complexes of U III and Ce III revealed that the UN bond distances are significantly shorter than the corresponding CeN distances.
