A uranylcontaining compound [U(CO_3)_3(H_2O)_2]·2H_2O has been synthesized under hydrothermal condition and characterized by X-ray single-crystal analysis. Crystal structural analysis indicates that this compound consists of three CO_3~(2-) molecules, one U~(6+). The results reveal that the title compound presents a 3D frame work built up by O-H……O week hydrogen bonds interactions. The central uranium atom is eight-coordinated through three CO_3~(2-) molecules and two H_2O. The compound shows a coplanar hexagonal network structure, each hexagon containing a hexagonal hole with a water moleculet.
