The complex UO~2(DOPOD)~2(NO~3)~2 has been prepared and characterized by elemental analysis and IR spectroscopy. The crystal structure of the complex has been determined by four-circle X-ray diffractometer. The complex crystal belongs to the orthorhombic system and space group Pbca, with cell parameters: a=0.9301(5) nm, b=1.7017(2) nm, c=5.1171(11) nm, V=8.099(5) nm^3, Z=8, D~c=1.478 g/cm^3, μ(MoK~α)=4.061mm^-^1, F(000)=3632, fina R=0.0655 and R~w=0. 1907 for 3006 observed reflections [I>2σ(I)]. The results indicate that uranyl ion is coordinated to six oxygen atoms, four of them are from two nitrate groups and other two are from carbonyl groups of organic ligands. The uranium atom in the structure is hexagonal bipyramid cooperated.
