我们报告了一种新型的Nb（V）-羧酸簇，该簇由乙醇铌（V）和新戊酸（三甲基乙酸）反应获得。单晶X射线衍射数据揭示了由16个Nb（V）离子组成的结构，其具有氧代-、乙氧基-和新戊酸根部分。新的簇表现出最高的核之间的结构特征的铌羧酸盐迄今报道。
We report a novel Nb(V)−carboxylate cluster obtained from reaction of niobium(V) ethoxide and pivalic (trimethylacetic) acid. Single crystal X‐ray diffraction data reveal a structure composed of 16 Nb(V) ions featuring oxo‐, ethoxy‐ and pivalate moieties. The new cluster exhibits the highest nuclearity among structurally characterized niobium carboxylates reported to date.
