4,5-Dibromo-1,2-dimethyl-1H-imidazol-3-ium bromide
Abstract
In the title salt, C5H7Br2N2+·Br−, the cation and anion are connected by an N—H...Br hydrogen bond. In the crystal, there are intercalated layers parallel to (10-2) in which bromide ions are located between the cations. Weak intermolecular C—H...Br hydrogen bonds are also observed.
