A new paper by Nico Giordano on "High-pressure polymorphism in Pyridine" has been published in IUCRj. The sequence of phases I→II→III has never been observed at high pressure in a single sample. Phases II and III can both be accessed reproducibly by crystal growth directly from the liquid phase. Phase II can also be accessed by decompression of phase III or from decompression of a pressure-amorphized sample. Publication date 21 Feb, 2020
