A new uranyl sulfate of composition Na6[(UO2)(SO4)4](H2O)4 has been synthesized at room temperature and its structure has been determined, along with a Raman spectroscopy characterization. The new compound is monoclinic, space group P21/c, with a 9.8005(3), b 9.7183(3), c 20.8263(6)A, beta 98.794(2)°, V 1960.27(10)A3, and Z=4. The structure was solved and refined from single-crystal X-ray diffraction data on the basis of F2 for 3996 unique reflections collected with monochromatic MoKa radiation to R(all) = 2.92%. The structure of this synthetic compound contains a uranyl sulfate cluster with com position [(UO2)(SO4)(4)](6-).
