Four inorganic-organic hybrid borates, K[BO(OH)(en)]·HO (, en = ethylenediamine), K[BO(OH)(1,3-dap)]·HO (, 1,3-dap = 1,3-diaminopropane), K[BO(OH)(1,6-dah)]·HO (, 1,6-dah = 1,6-diaminlhexane) and [(1,3-dap)Cd@BO(OH)]·0.5HO (), were made under solvothermal conditions. and are isostructural and feature a 2D layer built by BO(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 was obtained, which was composed of the same BO(OH) cluster layers as in and 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 was made in which the Cd-centered wheel cluster layers and 1,3-dap linkers were connected via Cd-N-C linkages.
在溶剂热条件下制备了四种无机-有机杂化硼酸盐，K[BO(OH)(乙二胺)]·H₂O (，乙二胺 = ethylenediamine)、K[BO(OH)(1,3-二氨基丙烷)]·H₂O (，1,3-二氨基丙烷 = 1,3-diaminopropane)、K[BO(OH)(1,6-二氨基己烷)]·H₂O (，1,6-二氨基己烷 = 1,6-diaminlhexane) 和 [(1,3-二氨基丙烷)Cd@BO(OH)]·0.5H₂O ()。 和 是同构的，其特征是由BO(OH)簇构建并通过B-N-C键由乙二胺和1,3-二氨基丙烷修饰的二维层。通过用更长且更灵活的1,6-二氨基己烷取代乙二胺和1,3-二氨基丙烷，得到了一种新型的氧硼簇有机骨架 ，它由与 和 中相同的BO(OH)簇层和1,6-二氨基己烷连接体组成。在相似的合成条件下，通过用过渡金属Cd取代碱金属K，制备了另一种类型的氧硼簇有机骨架 ，其中以Cd为中心的轮状簇层和1,3-二氨基丙烷连接体通过Cd-N-C键相连。
