摘要：

Sr3UO6, M(r) = 596.89, monoclinic, P2(1)/n. At room temperature, a = 6.0126 (2), b = 6.2138 (2), c = 8.6139 (3) angstrom, beta = 90.239 (2)degrees, V = 321.82 (3) angstrom3, Z = 2, D(x) = 6.160 (1) Mg m-3, muR = 0.12, lambda = 2.57155 (3) angstrom, R(wp) = 3.19%. The structure has been refined by Rietveld analysis of neutron powder diffraction data for 147 reflections. The structure is of a monoclinic GdFeO3-type perovskite. The octahedra are in complete order.
