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

Abstract

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 linkedviaweak C—H...O hydrogen bonds and π–π interactions [centroid–centroid distance = 3.743 (3) Å] involving inversion-related benzimidazole groups.
