| Abstract: The complex UO2[Bu2NCOCH2CONBu2](NO3)2 has been prepared by extration method.The molecular and crystal strueture of the complex have been determined by four-circle X ray diffractometer.The crystal cell parameters are found to be a=10.744(2),b=13.229(5), c=20.011(8)β, P=99.21(3)°,V=2808(2)β3. Z=4, Dc=1.709. cm-3. The crystal belongs to space group P21/c of monoclinic system. The result reveals that uranyl ion is coordinated to six oxygen atoms, four of them are from two nitrate groups and other two are from two carbonyl groups of organic ligand. Two nitrate groups are repulsed by six membered ring to the one side, so the structure or hexagonal bipyramid with center of uranium atom is distorted. |
