Abstract

The title salt, [NH3CH2CH2NH2]+·I-, has an array structure based on strong intermolecular N-HN hydrogen bonding formed between the ammonium and amine groups of adjacent cations. This interaction gives a helical chain of cations that runs parallel to the b axis. The four remaining NH group H atoms all form hydrogen bonds to the iodide anion, and these iodide anions lie in channels parallel to the cation-cation chains.
