摘　　要：One single crystal based on Th4＋ and cucurbit[6]uril （CB6） in nitric acid aqueous solutions was synthesized by slow evaporation method. The single crystal was characterized by elemental analysis, single crystal X-ray diffraction, XRD, FT-IR and TGA. The complexed cation of Th4＋ is a ten coordinated structure, in which the central thorium ion is coordinated by six monodentate water molecules and two bidentate nitrates. While CB6, as a second-sphere ligand, coordinates with the water molecules of [Th （NO3）2（H2O）6]2＋ through the formation of hydrogen bonding. Two other nitrate ions act as the counter anions. Besides, there are two free water molecules in the crystal system. The formation of the Th4＋-CB6 complex can contribute to the study of the coordination of CB6 and the extraction of Th4＋ in HN03 systemOne single crystal based on Th4＋ and cucurbit[6]uril （CB6） in nitric acid aqueous solutions was synthesized by slow evaporation method.
