title: Bis(1,3-dimethyl-1,3-diazinan-2-one)dinitratodioxidouranium(VI).
abstract: The title compound, [U(NO(3))(2)O(2)(C(6)H(12)N(2)O)(2)], exhibits a hexa-gonal-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 NO(3) (-) 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 -(CH(2))(3)- moiety in the DMPU ligand is disordered over two positions in a 0.786 (11):0.214 (11) ratio.
