Synthesis, crystal structure and Hirshfeld surface analysis of 1,1'-[oxybis(ethane-2,1-di-yl)]bis-(2-methyl-sulfanyl-1H-benzo[d]imidazole).

The asymmetric unit of the title compound, C(20)H(22)N(4)OS(2), consists of two independent mol-ecules, one of which is disordered. In each mol-ecule, the mean planes of the terminal benzimidazole moieties are inclined to one another by about 68°. In the crystal, tetra-molecular strands are generated by C-H⋯N hydrogen bonds and C-H⋯π(ring) inter-actions and are linked by C-H⋯π(ring) and π-stacking inter-actions.
