<b>The tetraiodopentabromide anionb> [Ib>4b>Brb>5b>]⁻ shows a different stereochemistry depending on the type of solvent used to crystallize it. This contrastive relationship is illustrated with a yin–yang drawing; the Dead Sea (yang) represents the ionic liquid [HMIM][Br] from which the syn-[Ib>4b>Brb>5b>]⁻ anion was crystallized. The Mediterranean Sea (yin) represents an organic solvent, dichloromethane, from which the anti-[Ib>4b>Brb>5b>]⁻ anion was isolated. Both isomers were characterized by single-crystal X-ray diffraction, Raman spectroscopy and quantum chemical calculations. More information can be found in the Communication by S. Riedel et al. on page 244 ff.
