Clark et al. recently reported the synthesis of the NpO[sub 2][sup +]ion encapsulated by the 18-crown-6 ligand. The [NpO[sub 2](18-crown-6)]ClO[sub 4] salt was characterized crystallographically and shown to have six approximately coplanar crown ether oxygen atoms coordinated to a central NpO[sub 2][sup +] unit. While the [UO[sub 2](18-crown-6)][sup 2+] species had been synthesized and characterized as the perchlorate salt previously, this is the first example of a transuranic crown inclusion complex. Motivated by this synthetic accomplishment and the prospect of similar chemistry involving the Pu analogues, we have undertaken theoretical studies of the series of actinyl inclusion complexes [AnO[sub 2](18-crown-6)][sup (1+,2+)], where An=U, Np, and Pu. © 2000 American Institute of Physics.

    The prospects of using chelating agents for increasing the excretion of actinides are reviewed. The removal of plutonium by chelating agents is of great importance because plutonium is extremely dangerous and induces cancer due to radiation toxicity. Similarly, uranium is a radionuclide, which...
