Abstract

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.
