In the title compound, [HgBr2(C15H17N5)], the HgII ion is tetrahedrally coordinated by two N atoms of the N-[1-(1H-benzimidazol-2-yl)ethylidene-κN]-3-(1H-imidazol-1-yl)propan-1-amine ligand, and two bromide anions. Intermolecular benzimidazole–imidazole N—HN hydrogen bonds link the molecules into helical chains along the b-axis direction and C—HBr hydrogen bonds link these chains into layers parallel to the bc plane.
