Abstract
The title compound, [U(NO3)2O2(C6H12N2O)2], exhibits a hexagonal–bipyramidal geometry around the UVI 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.
