摘要：

[Yb(NTO)(3)(H2O)(4)]. 6H(2)O was synthesized by mixing an aqueous solution of lithium 3-nitro-1,2,4-triazol-5-onate(LiNTO) and the dilute nitric acid solution of ytterbium oxide. The crystal structure has been determined by a four-circle X-ray diffractometer. The crystal is monoclinic, space group C2/c with crystal parameters a = 3.6931(5) nm, b = 0.6683(10) nm, c = 2.565g(3) nm, beta = 130.974(5)degrees, V = 4.7811(11) nm(3), Z = 8, d(c) = 2.013 g . cm(-3), mu = 4.1317 mm(-1), F(000) = 2850. The final R is 0.0258, the coordination number of Yb3+ is seven and the geometry of the ytterbium complex is pentagonal bipyramid.
