Cover Feature: Stepwise Stress‐Induced Transformations of Metal‐Organic Polyhedral Cluster‐Based Assemblies: Where Conformational and Supramolecular Features Meet (Chem. Eur. J. 55/2021)

Abstract

The understanding of multiple polymorphic phase transitions in molecular crystals is still in its infancy. With this in mind, single-crystal high-pressure X-ray diffraction studies were targeted at a polyhedral oxo cluster featuring phenyl rings in the outer sphere. Pressure evolution leads to a gradual relaxation of induced structural strains through stepwise conformational twisting of the phenyl rings with the reorganization of cooperative noncovalent interactions; this propagates the conformational isomerization.
