| 摘要: 以碱金属阳离子为结构导向剂，在溶剂热条件下合成了一个基于混合硼氧团簇单元及AlO4四面体构建的硼酸铝：Na2.5Rb[Al{B5O10}{B3O5}]·0.5NO3·H2O (1)。结构中，[B5O10]5-和[B3O7]5-两种单元交替连接形成一维[B8O15]n6n-链，链与链之间通过AlO4四面体连接形成具有七元环和十元环窗口的二维层，相邻取向相反的2个单层进一步通过B—O—Al键构成具有6种类型孔道的孔层结构。通过单晶X射线衍射、粉末X射线衍射、红外光谱、紫外可见漫反射光谱以及热重分析对该化合物进行了结构表征和性能研究。紫外可见漫反射光谱分析表明，化合物1的紫外吸收截止边为201 nm。 |

| Abstract: An aluminoborate, Na2.5Rb[Al{B5O10}{B3O5}]·0.5NO3·H2O (1), was synthesized under hydrothermal condition, which was built by mixed oxoboron clusters and AlO4 tetrahedra. In the structure, the [B5O10]5- and [B3O7]5- clusters are alternately connected to form 1D [B8O15]n6n- chains, which are further linked by AlO4 units to form a 2D monolayer with 7-membered ring and 10-membered ring windows. Two adjacent monolayers with opposite orientations further form a porous-layered structure with six channels through B—O—Al bonds. Compound 1 was characterized by single crystal X-ray diffraction, powder X-ray diffraction (PXRD), IR spectroscopy, UV-Vis diffuse reflection spectroscopy, and thermogravimetric analysis (TGA), respectively. UV-Vis diffuse reflectance analysis indicates that compound 1 shows a wide transparency range with a short cutoff edge of 201 nm, suggesting it may have potential application in UV regions. |
