Dimethyl 2,2′-[2,2′-bi(1H-1,3-benzimidazole)-1,1′-di­yl]diacetate

The whole mol­ecule of the title compound, C₂₀H₁₈N₄O₄, is generated by an inversion center. The benzimidazole ring mean plane make a dihedral angle of 89.4 (8)° with the plane passing through the acetate group (COO). In the crystal, mol­ecules are linked via weak C—H...O hydrogen bonds and π–π inter­actions [centroid–centroid distance = 3.743 (3) Å] involving inversion-related benzimidazole groups.
