摘要：

Single crystals of the compound K-8[(UO2)(2)(C2O4)(2)(SeO4)(4)] center dot 2H(2)O (I) are synthesized, and their structure is investigated using X-ray diffraction. Compound I crystallizes in the monoclinic system with the unit cell parameters a = 14.9290(4) angstrom, b = 7.2800(2) angstrom, c = 15.3165(4) angstrom, beta = 109.188(1)degrees, V = 1572.17(7) angstrom(3), space group P2(1)/n, Z = 2, and R = 0.0297. The uranium-containing structural units of crystals I are dimers of the composition [(UO2)(2)(C2O4)(2)(SeO4)(4)](8-), which belong to the crystal- chemical group AB(01)B(2)M(1) (A = UO22+, B-01 = C2O42- B-2 = SeO42- M-1 = SeO42-) of the uranyl complexes. The [(UO2)(2)(C2O4)(2)(SeO4)(4)](8-) dimers are joined into a three-dimensional framework through electrostatic interactions with the outer-sphere potassium cations.
