Iminodiacetic acid complexation with lanthanides under acidic conditions
The chemical behavior of the lanthanides and actinides generally converges with increasing number of f-electrons, but growing evidence suggests their chemistries begin to diverge after the f-shell is half-filled. Previous work with dipicolinic acid indicates that the degree of actinide covalent interaction increases at californium and berkelium. The shift in covalency may be unique to dipicolinic acid (DPA) or it may occur in similar ligands. Assessing the potential for covalent interactions with the structurally similar iminodiacetic acid (IDA) may provide an indication to the orbital interactions ...
