title: Ethyl 2-(1,3-benzodioxol-5-yl)-1-[3-(1H-imidazol-1-yl)prop-yl]-1H-benzimidazole-5-carboxyl-ate.
abstract: In the title compound, C(23)H(22)N(4)O(4), the essentially planar [maximum deviation = 0.022 (1) Å] benzimidazole ring system forms dihedral angles of 86.16 (7) and 37.38 (6)°, respectively, with the imidazole and benzene rings. The dioxolane ring adopts an envelope conformation with the methyl-ene C atom at the flap. In the crystal, C-H⋯O and C-H⋯N inter-actions link the mol-ecules into a ribbon along the a axis. The crystal packing is further stabilized by weak π-π stacking inter-actions [centroid-centroid distances = 3.5954 (8) and 3.7134 (8) Å] and C-H⋯π inter-actions.
