The synthesis and X-ray diffraction analysis of K{sub 2}(H{sub 5}O{sub 2})[UO{sub 2}(C{sub 2}O{sub 4}){sub 2}(HSeO{sub 3})] single crystals have been performed. This compound crystallizes in the triclinic system with the unit-cell parameters a = 6.7665(4) Angstrom-Sign , b = 8.8850(4) Angstrom-Sign , c = 12.3147(7) Angstrom-Sign , {alpha} = 94.73 Degree-Sign , {beta} = 90.16 Degree-Sign , {gamma} = 92.11 Degree-Sign , sp. gr. P1-bar, Z = 2, and R = 0.019. The basic structural units are island [UO{sub 2}(C{sub 2}O{sub 4}){sub 2}(HSeO{sub 3})]{sup 3-} groups, which belong to the AB{sub 2}{sup 01}M{sup 1} crystallochemical group of uranyl complexes (A = UO{sub 2}{sup 2+}, B{sup 01} = C{sub 2}O{sub 4}{sup 2-}, and M{sub 1} = HSeO{sub 3}{sup -}). Uraniumcontaining complexes are linked through K{sup +} and H{sub 5}O{sub 2}{sup +} ions and via a system of hydrogen bonds with the participation of oxonium hydrogen atoms in this structure.
