Synthesis and Crystal Structure of Bis(nitrate)bis(N-n-octyl-α-pyrrolidone)uranyl(Ⅱ)

摘要

The crystal structure of the title compound UO2(NO3)2[CH2(CH2)2CONC8H17] was determined by single-crystal X-ray diffraction. Crystal data: triclinic, space group P ī, a = 7.456(2), b = 8.371(2), c = 13.470(3)A, α = 95.66(1), β = 94.64(2), γ = 102.67(2)°, C24H46N4O10U, Mr = 788.68, V = 811.73A3, Dc = 1.613 g/cm3, Z = 1, F(000) = 390, μ = 5.052 mm-1, the final R = 0.0256 and wR = 0.0568 for 2826 observed reflections I>2σ(I). The central uranyl ions are coordinated by six oxygen atoms. Two of them are from the carbonyl groups of N-octyl--pyrrolidone molecules, and the other four from two nitrate groups.
