Abstract

A new hydrated magnesium borate, Mg(H2O)6B4O5(OH)4(H2O)3, was synthesized successfully by a facile slow evaporation method. Its structure was determined by single crystal X-ray diffraction, and it contains the functional building block (FBB) [B4O5(OH)4]. It possesses a short DUV cutoff edge (<175 nm) which benefits from the absence of dangling bonds in the crystal structure. Its properties were analyzed by IR spectroscopy and UV-vis-NIR diffuse reflectance spectroscopy. Moreover, theoretical calculations were carried out to analyze the relationship between the electronic structure and optical properties.

摘要

一种新的水合硼酸镁，Mg(H2O)6B4O5(OH)4(H2O)3，通过一种简单的缓慢蒸发方法成功合成。它的结构通过单晶 X 射线衍射确定，其中包含功能构建块（FBB）[B4O5(OH)4]。它具有较短的深紫外截止边缘（<175nm），这得益于晶体结构中不存在悬空键。其性质通过红外光谱和紫外可见近红外漫反射光谱进行分析。此外，还进行了理论计算来分析电子结构和光学性质之间的关系。
