四种无机-有机杂化硼酸盐K[B6 O 9（OH）（en）]中心点H2O（1，en =乙二胺），K[B6 O 9（OH）（1，3-dap）]中心点H2O（2，1，3-dap = 1，3-丙二胺），K[B6 O 9（OH）（1，6-dah）（0.5）]中心点H2O（3，1，6-dah = 1，6-二氨基己烷）和[（1，3-dap）Cd@B5O8（OH）]中心点0.5H（2）O（4）。1和2是同构的，其特征在于由B6 O 9（OH）簇构建的2D层，并通过B-N-C键被en和1，3-dap修饰。通过用更长和更柔性的1，6-dah取代en和1，3-dap，得到了一种新型的氧代硼簇有机骨架3，其由与1和2相同的B6 O 9（OH）簇层和1，6-dah连接体组成。通过在类似的合成条件下用过渡金属Cd取代碱金属K，制备了另一种类型的氧代硼簇有机框架4，其中Cd中心的轮簇层和1，3-dap连接基通过Cd-N-C键连接。
Four inorganic-organic hybrid borates, K[B6O9(OH)(en)]center dot H2O (1, en = ethylenediamine), K[B6O9(OH)(1,3-dap)]center dot H2O (2, 1,3-dap = 1,3-diaminopropane), K[B6O9(OH)(1,6-dah)(0.5)]center dot H2O (3, 1,6-dah = 1,6-diaminlhexane) and [(1,3-dap)Cd@B5O8(OH)]center dot 0.5H(2)O (4), were made under solvothermal conditions. 1 and 2 are isostructural and feature a 2D layer built by B6O9(OH) clusters and modified by en and 1,3-dap via B-N-C linkages. By replacing en and 1,3-dap with longer and more flexible 1,6-dah, a new type of oxoboron cluster organic framework 3 was obtained, which was composed of the same B6O9(OH) cluster layers as in 1 and 2 and 1,6-dah linkers. By replacing alkali metal K with transition metal Cd under similar synthetic conditions, another type of oxoboron cluster organic framework 4 was made in which the Cd-centered wheel cluster layers and 1,3-dap linkers were connected via Cd-N-C linkages.
