摘　　要：采用水热法制备了h-MoO3·1/3H2O(化合物(1)),通过单晶X射线衍射对h-MoO3·1/3H2O的结构进行了进一步的确定,分析表明化合物h-MoO3·1/3H2O的结构基于由MoO6八面体形成的双链,通过共价键的结合形成了具有三维层状结构的多孔化合物,在化合物中含有由12元环和3元环堆积而成的两种隧道,其中水分子占据了12元环隧道.另外,作者研究了化合物(1)的红外光谱和拉曼光谱性质,并与其它相的化合物进行了对比.Metastable hexagonal molybdenum trioxide hydrate, MoO3·1/3H2O, has been hydrothermally synthesized and characterized by Single-crystal X-ray diffraction, IR, Raman. The structure of compound is based on double chains of MoO6 octahedra bonded together with oxygen atom into a three-dimensional frameworks and porous molybdenum trioxide, in which two kinds of 1D tunnel exist. The one tunnel consists of hexagonal 12-member-ring defined by twelve {MoO6} octahedra, where the free water molecules were located. The other consists of 3-member-ring defined by three {MoO6} octahedra. Additionally, IR and Raman apectra were employed to compare its structure with the known similar compounds.
