摘要：

An X-ray diffraction study of Rb[UO2(SeO4)F] •H2O (I) was performed. The compound crystallizes in the rhombic system with the following unit cell parameters: a = 8.4753(6), b = 13.5234(9), c = 13.5296(9) Å, space group Pnma, Z = 8, V = 1550.7(2) Å3; R = 0.0248. The principal structural units of crystals of I are [UO2(SeO4)F]- layers belonging to crystal-chemical group AT3M2 (A = UO 2 2+, T3 = SeO 4 2-, M2 = F-) of uranyl complexes. The uranium-containing layered units are combined via electrostatic interaction with Rb cations and via a system of hydrogen bonds involving outer-sphere water molecules. © 2011 Pleiades Publishing, Ltd.
