A rare and novel Cr-substituted polyoxoniobate (PONb), [CrNbO(OH)(HO)], has been synthesized by a combination of hydrothermal and conventional solution methods. The PONb shows an unknown tetrameric structure, which is the largest Cr-containing PONb to date. Interestingly, every two PONb tetramers can be joined together by alkali-metal cations to form a discrete cubelike ionic cluster. The obtained PONb not only enriches the very limited members of the Cr-substituted PONb family but also exhibits high ionic conductivity.
一种罕见的新型 Cr 取代的多铌酸盐（PONb），[CrNbO(OH)(HO)]，通过水热和常规溶液方法的组合合成。该 PONb 表现出未知的四聚体结构，这是迄今为止最大的含 Cr 的 PONb。有趣的是，两个 PONb 四聚体可以通过碱金属阳离子连接在一起，形成离散的立方离子簇。所得到的 PONb 不仅丰富了有限的 Cr 取代的 PONb 家族成员，而且还表现出高的离子电导率。
