title: A triple helical structure supported solely by C-H···O hydrogen bonding.
abstract: A novel triple helical structure that is self-assembled by cationic molecules, 1-acetamido-3-(2-pyrazinyl)-imidazolium, is reported. The computational analysis underpins that the formation of the triple helix is driven by C-H···O hydrogen bonding.
