Syntheses and structures of a new 2D layered borate and a novel 3D porous-layered aluminoborate

Abstract

Two new layered and porous-layered borates ([H2dap][B7O11(OH)] (1, dap = 1,2-propanediamine) and [H3O]K3.52Na3.48{Al2[B7O13(OH)][B5O10][B3O5]}[CO3] (2)) have been solvothermally made. 1 features a 2D layer made of the [B7O13(OH)]6− cluster, in which H2dap is located in the windows of the layers. The fundamental building block (FBB) [B7O13(OH)]6− 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, [B7O13(OH)]6−, [B5O10]5− and [B3O7]5−, respectively. The strict alternation of the different oxoboron clusters and AlO4 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.
