T. Suzuki, T. Kawasaki and Y. Ikeda

Abstract: The title compound, [U(NO₃)₂O₂(C₆H₁₂N₂O)₂], exhibits a hexagonal-bipyramidal geometry around the U^VI ion, which is situated on an inversion centre and coordinated by two oxide ligands in the axial positions, and four O atoms from two bidentate NO₃^- and two O atoms from two 1,3-dimethyl-1,3-diazinan-2-one (DMPU) ligands in the equatorial plane. These ligands are located in trans positions. The -(CH₂)₃- moiety in the DMPU ligand is disordered over two positions in a 0.786 (11):0.214 (11) ratio.
