摘要：
The complex Na6[(UO2)3O(OH)3(SeO4)2]2 · 10H2O (I) is synthesized and studied by X-ray diffraction. The compound crystallizes in the orthorhombic crystal system with the unit cell parameters: a = 14.2225(7) Å, b = 18.3601(7) Å, c = 16.5406(6) Å, V = 4319.2(3) Å3, Z = 4, space group Cmcm, R1 = 0.0406. Compound I is found to be a representative of the crystal-chemical group A3M3M23T32 (A = UO2+2, M3 = O2−, M2 = OH−, T3 = SeO2−4) of the uranyl complexes; it contains layer uranium-containing groups [(UO2)3O(OH)3(SeO4)2]3−. These layers linked to form a three-dimensional cage through bonds formed by the sodium atoms with the oxygen atoms of the uranyl ions and SeO4 groups that belong to different layers.
