摘要
The title compound, C(22)H(17)N(3)O(4), was prepared through 1,3-dipolar cycloaddition: the dihedral angle between the benzimidazole and benzene rings is 80.93 (6)degrees. The crystal structure is stabilized by weak pi-pi interactions between the planar pyrrolobenzimidazole rings (r.m.s. deviation = 0.0293 angstrom) of neighbouring molecules, forming chains along the c axis. The perpendicular distance is 3.47 (2) angstrom and the centroid-centroid distances are in the range of 3.590 (3) - 3.944 (3) angstrom.
