The title compound, C(21)H(22)Br(2)N(4)·0.5H(2)O, contains two benzimidazole groups which may provide two potential coordination nodes for the construction of metal-organic frameworks. The mean planes of the two imidazole groups are almost perpendicular, with a dihedral angle of 83.05 (2)°, and adjacent mol-ecules are linked into a one-dimensional chain by π-π stacking inter-actions between imidazole groups of different mol-ecules [centroid-to-centroid distances of 3.834 (2) and 3.522 (2) Å].
