(1-Hy-droxy-ethyl-idene)(meth-yl)aza-nium bromide-N-methyl-acetamide (1/1).

The asymmetric unit of the organic hybrid salt, C(3)H(8)NO(+)·Br(-)·C(3)H(7)NO, comprises an N-methyl-acetamide cation, a N-methyl-acetamide mol-ecule 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.
