The asymmetric unit of the title compound, C16H16N4O2S, contains two molecules (A and B) with similar conformations: the benzene rings are oriented at dihedral angles of 80.94 (10)° and 84.54 (10)° with their adjacent 1H-benzimidazole groups. In the crystal, the molecules are connected by N—H...N hydrogen bonds, forming separate C(4) chains of both the A and B molecules along [010]. The A and B chains are cross-linked by several C—H...O interactions involving the benzene rings and the sulfonyl groups, which lead to R21(5) loops in the linkage of the chains.
