Abstract

The discovery of new borates with unique structures has always been a growing part of solid-state chemistry, especially for polyborates. Herein, a new aluminoborate, CsAlBO, has been discovered by a high-temperature solution in a vacuum system. The highly polymerized [BO] cluster, unlike the annular configuration in previously reported polyborates, is found in CsAlBO for the first time. The different linkage reflected by the local symmetry in cluster makes these borates not isotypic, although the formula of [BO] is identical. Experimental measurement performed on CsAlBO powder reveals the deep-ultraviolet transparent spectral feature.

摘要

具有独特结构的新型硼酸盐的发现一直是固态化学中不断发展的一部分，尤其是对于聚硼酸盐而言。在此，通过真空系统中的高温溶液法发现了一种新型铝硼酸盐CsAlBO。首次在CsAlBO中发现了高度聚合的[BO]簇，它不同于先前报道的聚硼酸盐中的环状结构。尽管[BO]的化学式相同，但簇中局部对称性所反映的不同连接方式使得这些硼酸盐并非同型。对CsAlBO粉末进行的实验测量揭示了其深紫外透明光谱特征。
