Sažetak
Six novel co-crystals of tetrabromoquinone with iodide salts of organic cations displaying short contacts between iodide anions and the quinoid rings have been structurally characterised. Sandwich-like groups I−⋯quinone⋯I− are present in all of them ; competition of this motif with halogen bonding has been described for the first time. The black colour of the crystals indicates charge transfer from the iodide to the quinoid ring, which is interpreted as n → π*. Intermolecular interactions were analysed using Hirshfeld surfaces and Voronoi–Dirichlet polyhedra.
