2-Ethyl-4-methyl-1 H -imidazol-3-ium bromide.

In the title mol-ecular salt, C 6 H 11 N 2 + ·Br - , the components are linked by N-H⋯Br⋯H-N hydrogen bonds into C (8)chains of alternating cations and anions propagating in the b -axis direction; these chains are cross-linked in the c -axis direction by weak C-H⋯Br hydrogen bonds.
