【Abstract】 The complex UO2(DDPEZ)(NO3)2 has been prepared and characterized by IR spectroscopy and XPS spectra. The crystal structure of the complex has been determined by X-ray diffraction. The crystal belongs to Triclinic system and space group P1, with cell parameters: a=0.664 2(3) nm, b=0.805 0(2) nm, c=1.515 6(5) nm, α=104.39(2)°, β=91.13(3)°, γ=94.84(3)°, and V=0.781 4(5) nm3, Z=2, Dc=1 676 kg·m-3, μ(Mo Kα)=0.071 073 nm, F(000)=390, final R=0.037 9 and wR=0.091 7 for observed reflections[I>2σ(I)]. The results indicated that uranyl ion is coordinated with six oxygen atoms, four of them from two nitrate groups and two from carbonyl groups of different organic ligands. CCDC: 284452.更多还原
