Formation of a Thermally Stable, Porous Coordination Network via a Crystalline-to-Amorphous-to-Crystalline Phase Transition

Abstract

A porous coordination network was cleanly obtained after a crystalline-to-amorphous-to-crystalline phase transition, and the crystal structure was unambiguously solved by ab initio powder X-ray diffraction. After the solid-state phase transition, the porous structure was remarkably stable up to 673 K and capable of reabsorbing various guest molecules, such as aromatic solvents and I-2.
