摘　　要：The uranyl complex [UO2（PMBP）2（DMDBU）]（HPMBP=1-phenyl-3-methy1-4-benzoyl-pyrazolone-5,DMDBU=N,N′-dimethyl-N,N′-dibenzenyl-urea）was synthesized and characterized.The structure was determined by single X-ray diffraction analysis.The crystal belongs to triclinic system,space group P（1）-.The crystallographic data are:a=9.5947（10）,b=12.0531（11）,c=20.002（2）,α=77.167（7）,β=80.090（8）,γ=75.870（7）°,V=2170.1（4）3,Z=2,F（000）=1052,Mr=164.92,Dc=1.630 Mg/m3,μ=3.800mm-1,R1=0.0409,wR2=0.0770.In the crystal,the uranyl ion is coordinated by four oxygen atoms from two PMBP ligands and one oxygen atoms from one DMDBU to form a distorted pentagonal-bipyramid geometry.The uranyl complex [ UO2 （PMBP） 2 （DMDBU） ] （ HPMBP = 1 - phenyl - 3 - methyl - 4 - benzoyl - pyrasolone - 5, DMDBU = N, N＇ - dimethyl - N, N＇ - dibenzenyl - urea） was synthesized and characterized. The structure was determined by single X-ray diffraction analysis. The crystal belongs to triclinic system, space group P 1. The crystallographic data are： a =9. 5947 （10）, b=12.0531 （11）, c=20.002 （2） A, α=77.167 （7）, β=80.090 （8）, γ=75.870 （7）°, V= 2170.1 （4） A^3, Z=2, F （000） =1052, Mr=164.92, Dc=1.630 Mg/m^3, p,=3.800mm^-1, R1 =0.0409, wR2 = 0. 0770. In the crystal, the uranyl ion is coordinated by four oxygen atoms from two PMBP ligands and one oxygen atoms from one DMDBU to form a distorted pentagonal - bipyramid geometry.
