摘要
配合物[UO2(Bu2NCOCH2CONBu2)(NO3)2]晶体属单斜晶系,P21/c空间群,a=10.744(2),b=13.229(5),c=20.011(8)A,β=99.21(3)°,V=2808(2)A3,Dc=1.07g·cm(-3),Z=4,配合物分子中具有直线结构的铀酰离子由六个氧原子配位,其中四个来自硝酸根,另外两个来自羰基,形成平面六角形,六角形的平面与铀酰离子的直线垂直,两个硝酸根处于相邻位置.
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)A, P= 99.21(3)°,V= 2808(2)A3. 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.
