The bromine anions are placed on both sides of heterocyclic cation and form Br⋯N contacts of 3.674 (9) and 3.860 (9) Å, which confirms the location of positive charge on the N atom. Non-classical inter-molecular C-H⋯Br inter-actions stabilize the three-dimensional crystal structure. Moreover, anion⋯π inter-actions are noted [Br⋯ring centroid range = 3.367 (9)-3.697 (9) Å]. The partly saturated heterocycle is disordered over two sofa conformations with occupancies in the ratio 0.56 (2):0.44 (2).Acta crystallographica.
