Abstract
The asymmetric unit of the organic hybrid salt, C3H8NO+·Br−·C3H7NO, comprises an N-methylacetamide cation, a N-methylacetamide molecule and a bromide anion. The amide species are linked head-to-head through a short O⋯H⋯O hydrogen bond, giving a monocation, which is extended by N—H⋯Br hydrogen bonds into chains along the b-axis direction.
