文摘

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.
