1,3-Diprop-2-ynyl-1H-imidazol-3-ium bromide

In the title salt, C9H9N2+·Br−, the ethynyl groups are nearly antiparallel to each other [the angle between the two ethynyl groups is179.7 (2)°]. No classical hydrogen bonds or π–π interactions are observed. The molecules are linked by C—H...Br hydrogen bonds. The bromide anions are involved in interactions with three H atoms
