Abstract

The crystal matrix of N-methyl-3,5-dibromopyridinium iodide is constituted of infinite helices where the cation and the anion alternate and are bound by the second shortest reported C–Br⋯I halogen bonding. The electron poor pyridinium scaffold is particularly effective in boosting the electron acceptor ability of bromine substituents.
