摘要：
[U(C7H5O2)2O2], M(r) = 512.26, monoclinic, C2/m, a = 7.604 (2), b = 17.408 (3), c = 5.296 (2) angstrom, beta = 95.81 (2)-degrees, V = 697 (2) angstrom 3, Z = 2, D(x) = 2.44 Mg m-3, lambda(Mo K-alpha) = 0.71069 angstrom, mu = 11.0 mm-1, F(000) = 468, room temperature, R = 0.058 for 946 observations with I > 3-sigma(I). The uranyl ion has a fourfold coordination. The cordination polyhedron around the uranium center approximates to an octahedron with the carboxylate groups acting as bridging donors.
