Description

The crystal structures of UVO5 [space group Pbcm, a= 4.1231(1) A, b=12.3641(1) A, c=7.2071(1) A, Z=4] and Cs2(UO2)2V2O8[space group P21/a, a 10.521(2) A, b= 8.4369(9) A, c = 7.308(3) A, β 106.08(1)o, Z = 2], previously obtained by single-crystal X-ray diffraction were refined using powder neutron diffraction and Rietveld analysis adapted to time-of-flight data. The main structural features of the two compounds were confirmed but more accurate oxygen positions are reported here. (Author)
