Two new layered and porous-layered borates ([Hdap][BO(OH)] (1, dap = 1,2-propanediamine) and [HO]KNa{Al[BO(OH)][BO][BO]}[CO] (2)) have been solvothermally made. 1 features a 2D layer made of the [BO(OH)] cluster, in which Hdap is located in the windows of the layers. The fundamental building block (FBB) [BO(OH)] cluster in 1 represents a new type of FBB of the hepta-borate family. 2 is a novel aluminoborate with a 3D porous-layered structure formed by three types of oxoboron clusters, [BO(OH)], [BO] and [BO], respectively. The strict alternation of the different oxoboron clusters and AlO tetrahedra leads to the abundant channel systems of the structure. 2 is the first aluminoborate (ABO) containing three types of oxoboron clusters and the first 3D porous-layered ABO with seven types of channels. UV-vis diffuse reflectance spectra reveal that both of them are wide band-gap semiconductors and have potential applications in UV regions.
通过溶剂热法制备了两种新型的层状和多孔层状硼酸盐（[Hdap][BO(OH)]（1，dap = 1,2 - 丙二胺）和[HO]KNa{Al[BO(OH)][BO][BO]}[CO]（2））。1具有由[BO(OH)]簇构成的二维层，其中Hdap位于层的窗口中。1中的基本结构单元（FBB）[BO(OH)]簇代表七硼酸盐家族的一种新型FBB。2是一种新型铝硼酸盐，具有由三种类型的氧硼簇[BO(OH)]、[BO]和[BO]分别形成的三维多孔层状结构。不同氧硼簇和AlO四面体的严格交替导致了该结构丰富的通道体系。2是第一种包含三种类型氧硼簇的铝硼酸盐（ABO），也是第一种具有七种类型通道的三维多孔层状ABO。紫外可见漫反射光谱表明它们都是宽带隙半导体，在紫外区域具有潜在应用。
