3D electron diffraction analysis of a novel, mechanochemically synthesized supramolecular organic framework based on tetra­kis-4-(4-pyridyl)phenyl­methane

Tetra­kis-4-(4-pyridyl)­phenyl­methane (TPPM) is a tetrahedral rigid molecule that crystallizes forming a dynamically responsive supramolecular organic framework (SOF). When exposed to different stimuli, this supramolecular network can reversibly switch from an empty to a filled solvated solid phase. This article describes a novel expanded form of a TPPM-based SOF that has been mechanochemically synthesized and whose crystal structure has been determined by 3D electron diffraction analysis using a novel electron diffractometer.
