摘要：
Trilead undecauranate, Pb3U11O36, M(r) = 3815.88, orthorhombic, Pmmn. At T = 295 K, a = 28.459 (1), b = 8.3790 (3), c = 6.7650 (3) angstrom, V = 1613.2 (1) angstrom3, Z = 2, D(x) = 7.854 Mg m-3, muR = 0.11, lambda = 2.5700 (1) angstrom, R(p) = 2.94, R(wp) = 3.99%. The structure has been refined by Rietveld analysis of neutron powder diffraction data for 427 reflections. The structure is closely related to alpha-U3O8.
