摘　　要：合成了UO_2[CH_2(CH_2)_4CONC_2H_5]_2(NO_3)_2,对配合物进行了元素分析、摩尔电导、热重分析,紫外、红外等测试,并经X-射线单晶结构分析,确定了配合物的结构.配合物晶体属三斜晶系,空间群为P(?),a=7.171(2),b=8.655(3),c=10.182(5)(?),α=78.27(3),β=70.63(3),γ=81.76(3)°,V=581.7(4)(?)~3,Z=1,D_c=1.94g.cm^(-3),R=0.0218.配合物分子中铀原子由八个氧原子配位构成六方双锥多面体.The complex UO_2[CH_2(CH_2)_4CONC_2H_5](NO_3)_2 has been prepared in organic solvent and characterized by microanalysis, molar conductance, TG-DTG as well as UV and IR spectra. The molecular and crystal structure of the complex has been determined by fourcircle X-ray diffractomcter. The crystal belongs to space group P1 of triclinic system. Its crystal cell parameters are a = 7.171(2), b = 8.655(3), c = 10.182(5)A, α = 78.27(3), β = 70.63(3), γ = 81.76(3)° , V=581.7(4)A3, Z= 1, Dc= 1.94g · cm-3. R = 0.0218 for 2286 unique reflections [I> 1.5(δ(I0)]. The molecular structure consists of a uranium atom coordinated to eight oxygen atoms and with them form approximately a hexagonal bipyramid coordinating polyhedron.
