基于组装合成的思想,在水热条件下合成了一种水合铵硼酸盐.将孤立的硼氧聚阴离子通过聚合脱水自组装形成一维链状结构,链与链之间通过氢键作用形成硼酸盐层,铵离子和水分子填充在阴离子的骨架间隙中,并通过氢键将硼酸盐层连接起来.使用红外光谱、元素分析、热重-差热分析及X射线单晶衍射分析等手段,对该化合物结构进行了表征.单晶结构分析结果与假想结果相吻合,该化合物系孤立的五硼氧聚阴离子通过缩聚脱水形成一维无限链状结构,链与链之间通过氢键连接在一起,铵离子和水分子填充在骨架间隙当中.该化合物属三斜晶系,P-1空间群,晶胞参数a=0.76413(15) nm,b=0.92529(19) nm,c=1.1949(2) nm,α=99.49(3)°,β=105.87(3)°,γ=91.57(3)°.
Under hydrothermal conditions,A hydrated ammonium hydroxy-borate was synthesized based on "Scale Chemistry". Isolated borate anions self-assemble via polymerization to form one dimensional infinite chain, which are linked by hydrogen bonds to form borate sheets. Ammonium ions and water molecules between these sheets connect adjacent sheets via hydrogen bonds. The compound has been characterized by infrared spectroscopy, elemental analysis, and thermogravimetric analysis as well as single crystal X-ray diffraction studies. The results of single crytal X-ray diffraction analysis are in agreement with the results of hypothesis. The compound exhibits an one-dimensional infinite chain that is formed via polymerization of pentaborate anions, with the guest ammonium ions and water molecules residing in the framework. The compound crystallizes in the triclinic system with space group P-1,a=0.76413(15) nm, b=0.92529(19) nm,c=1.1949(2) nm,α=99.49(3)°,β=105.87(3)°and γ=91.57(3)°
