Description
β-UO2SO4, monoclinic, P21/c,a=6.760 (1), b=5.711 (1), c=12.824(4) A, β=102.91 (2)0, V= 482.6 A3, Z=4, Dsub(c) =5.04 g cm-3. α-UO2SeO4, monoclinic, P21/c,a=6.909 (1), b=5.525 (1), c=13.318 (3) A, β=103.79 (2)0, V=493.7 A3, Z=4, Dsub(c)=5.569 g cm-3. β-UO2SeO4, monoclinic, P21/c, a=6.979 (1), b=5.795 (1), c=13.235 (2) A,β=103.71 (2)0, V=520.0 A3, Z=4, Dsub(c)=5.279 g cm-3. The stcutures of the isostructural title compounds have been solved from X-ray and neutron diffraction powder data. U atoms are coordinated by pentagonal bipyramids of O atoms. Remarkably, a uranyl O atom of one bipyramid belongs to the pentagonal base plane of the next. (Auth.)
