摘要：
The synthesis and X-ray diffraction analysis of K-2(H5O2)[UO2(C2O4)(2)(HSeO3)] single crystals have been performed. This compound crystallizes in the triclinic system with the unit-cell parameters a = 6.7665(4) , b = 8.8850(4) , c = 12.3147(7) , alpha = 94.73A degrees, beta = 90.16A degrees, gamma = 92.11A degrees, sp. gr. P (1) over bar, Z = 2, and R = 0.019. The basic structural units are island [UO2(C2O4)(2)(HSeO3)](3-) groups, which belong to the AB (2) (01) M (1) crystallochemical group of uranyl complexes (A = UO (2) (2+) , B (01) = C2O (4) (2-) , and M (1) = HSeO (3) (-) ). Uraniumcontaining complexes are linked through K+ and H5O (2) (+) ions and via a system of hydrogen bonds with the participation of oxonium hydrogen atoms in this structure.
