Abstract

Successful synthesis of the first transuranium Metal-Organic Frameworks (MOFs) involving neptunium(IV) (Np(IV) is reported. These compounds were obtained from the controlled hydrolysis of Np(IV) in the presence of dicarboxylate ligands. The final structures contain the [Np6O4(OH)4(H2O)6]12+ unit, which were never cristallized before with tetravalent neptunium, associated with ditopic ligands.
