摘　　要：合成了含有十钒酸阴离子的超分子化合物[Na(DB18C6)(H2O)2]3.V10O2.8[CH3OH].[H3O]3并通过X射线衍射分析、IR光谱及元素分析对其结构进行了表征.单晶X射线衍射分析表明化合物属于单斜晶系,P21/m空间群,a=15.5520(16)nm,b=18.7581(19)nm,c=16.3619(18)nm,β=109.0390(10),V=4512.1(8)nm3,Z=2,F(000)=2380,R1=0.0606,wR2=0.1312.化合物的晶体结构单元由一个无质子化的十钒酸根多阴离子、一个甲醇分子、3个[Na(DB18C6)(H2O)2]+和3个H3O+阳离子组成,并且彼此之间通过静电力和氢键形成稳定的三维结构.[Na（DB18C6） （H2O）2]3·V10O28·[CH3OH]·[H3O]3 was sythesized at room temperature. The complex was characterized by IR, and elemental analysis and X- ray diffraction single crystal structure analysis. Crystal structure analysis showed that complex belongs to monoclinic, space group P2_1/m, a = 15.5520 （16） nm, b = 18.7581（19）nm, c=16.3619（18） nm, [3=109.0390（10）, V = 4512.1（8）nm3, Z = 2, F（000） =2 380, R1=0. 0 606, wR2 =0. 1 312. The complex consists of five basic uints, which are Na＋CH3OH,DB18C6 , V10 O28^16- and H3O＋. Sodium ion was located in the cavity of dibenzo-18-crown-6, And each other through electrostatic and hydrogen bonds to form a stable three-dimensional structure.
