通过添加简单的添加剂，得到了两种新型的五唑钠骨架(即MPF-3和MPF-4)。MPF-3展示了具有沸石MTN拓扑结构的美学三维(3D)框架，具有Na28N80和Na20N60纳米笼。在MPF-4分子筛中，两个左旋螺旋链构筑了填充了二甲基砜分子的封闭同手性通道，构成了类沸石的UNJ拓扑结构。重要的是，这两种化合物的制备为探索五唑阴离子独特的对称结构和多种配位方式提供了有效的实验手段，并证明了通过适当的添加剂来调节晶体结构是可能的。
Two novel sodium-pentazolate frameworks (namely, MPF-3 and MPF-4) were achieved by adding simple additives. MPF-3 exhibits an aesthetic three-dimensional (3D) framework with the zeolitic MTN topology, featuring Na28N80 and Na20N60 nanocages. In MPF-4, two left-handed helical chains construct enclosed homochiral channels filled with dimethyl sulfone molecules, which constitute a zeolite-like UNJ topology. Importantly, the preparation of these two compounds provides an effective experimental means to explore the unique symmetrical structure and multiple coordination modes of pentazolium anion and demonstrates that it is possible to regulate the crystal structure through appropriate additives.
