We report a Johnson hexadecahedronal coordination cage, constructed via 10 Ni4-p-tert-butylthiacalix[4]arene (Ni4-TC4A) units as vertices and 16 5-(pyridin-4-yl)isophthalate (PIP) ligands as tiles. It features a gyroelongated square bipyramidal geometry, equivalent to two square pyramids pillared by a square antiprism, a J17 Johnson solid. Remarkably, the cage compound exhibits a much higher uptake capacity of C3H8 than CH4, representing a promising material for separation of these two gases. In contrast, Co4-TC4A units are linked by PIP ligands and rare {Co4O4Cl2} clusters, providing a one-dimensional bamboo stick-like polymer.
我们报告了一个约翰逊十六面体形配位笼，由 10 个 Ni4-对叔丁基硫杂杯[4]芳烃（Ni4-TC4A）单元作为顶点和 16 个 5-（吡啶-4-基）间苯二甲酸（PIP）配体作为瓦片构建而成。它具有陀螺状的正方形双锥几何形状，相当于两个由正方形反棱柱体支撑的正方形金字塔，是 J17 约翰逊固体。值得注意的是，笼状化合物对 C3H8 的吸附容量比 CH4 高得多，是分离这两种气体的有前途的材料。相比之下，Co4-TC4A 单元由 PIP 配体和罕见的 {Co4O4Cl2} 簇连接，提供了一维竹棒状聚合物。
