摘要
合成了UO_2(PMBP)_2HMPA(PMBP=1-苯基-3-甲基-4-苯甲酰基-吡唑啉酮-5,HMPA=六甲基磷酰胺),测定了该配合物的元素组成、红外光语、质子核磁共振谱及晶体结构。该晶体属于单斜晶系,空间群为P2_1,a=1.1468(5)nm,b=1.4777(2)nm,c=1.4056(6)nm,β=100.91(4)°,V=2.3389nm ̄3,D_c=1.43g/cm ̄3,Z=2,F(000)=979.85。在配合物中,U原子采用七配位,其配位多面体为扭曲的五角双锥。
The complex UO2(PMBP)2 HMPA was synthesized, where PMBP=1-phehyl-3-methyl-4-benzoyl-pyrazolone-5 and HMPA=hexamethylphosphoramide. The reaction product has been characterized by elemental analyses, infrared spectra and 1H NMR.The singal-crystal Xray determination shows that the crystal belongs to a monoclinic system, space group is P21 with a=1. 1468 (5)nm. b=1.4777 (2) nm. c=1.4056 (6) nm,β=100.91 (4)°,v=2.3389nm3,Dc=1.43g/cm3, Z=2, the finial R=0.0675. The coordination polyhedron is a pentagonal bipyramid in which the uranium atom is seven-coordinated and the almost linear uranyl group is perpendicular to its equatorial plane.
