We describe a two-component cocrystal composition which appears in two stoichiometric variations exhibiting different supramolecular architectures: whereas one stoichiometric variation displays C–HO hydrogen bonds, the second form exhibits short IO halogen bonds alongside Iπ halogen-bonded contacts; the two forms are readily prepared mechanochemically by varying the relative amounts of starting materials in a liquid-assisted grinding process.
