Abstract

Successful synthesis of the first transuranium metal-organic frameworks (TRU-MOFs) involving tetravalent Np4+ is reported. These compounds were obtained from the controlled hydrolysis of Np4+ in the presence of dicarboxylate ligands. The final structures contain the [Np6O4(OH)4(H2O)6]12+ unit, which were never crystallized before with tetravalent neptunium, associated with ditopic ligands.
