TL;DR: The results show that mechanochemical syntheses and transformations of ZIFs are consistent with Ostwald's rule of stages and proceed toward thermodynamically increasingly stable, more dense phases.

TL;DR: The authors demonstrate the formation of two-component cocrystals based on halogen bonds with phosphorus, arsenic and antimony, which is an advance in supramolecular chemistry and opens up opportunities in materials science, as shown by colossal thermal expansion of the cocrystal involving I···Sb halogen bond.

TL;DR: In this article, mechanochemical cocrystallization was used to prepare fluorescein cocrystals involving pyridyl-based cocrystal formers, which exhibit different crystal structures, thermal and optical properties than those obtained via solution-based crystallisation.

TL;DR: A polymorph screen on a new 1:1 co-crystal of caffeine, C8H10N4O2, with anthranilic acid, has revealed a rich diversity of crystal forms (two polymorphs, two hydrates and seven solvates, including two sets of isostructural solvate).

TL;DR: A series of theophylline cocrystals involving fluorobenzoic acids was prepared and structurally characterised in this paper, showing that without the use of first-principles crystal structure prediction methods, it is remarkably difficult to predict and understand the outcomes of cocrystallization attempts involving small and rigid molecules.
