Halogen bonding in chloroiodates(iii)

Abstract

Oxidation of iodides of organic cations by dichlorine in aqueous HCl results in salts of tetrachloroiodate(III) [ICl₄]⁻. Within this series of compounds, the formation of halogen bonding between the iodine and chlorine atoms is common, leading to the assembly of supramolecular associations in the solid state. The nature of these interactions was examined by theoretical methods.
