Abstract: The title compound, C7H14BrN2+·Br-, was prepared by nucleophilic substitution of DABCO (systematic name: 1,4-diazabicyclo[2.2.2]octane) with dibromomethane in acetone. The structure features BrH close contacts (2.79 and 2.90 Å) as well as a weak bromine-bromide interaction [3.6625 (6) Å].
