1-Tosyl-2-[(1-tosyl-1H-benzimidazol-2-yl)methyl-sulfanyl]-1H-benzimidazole

In the title compound, C(29)H(24)N(4)O(4)S(3), the two N-tosyl-benzimidazolyl unit are connected through a -S-CH(2)- fragment, the dihedral angle between the benzimidazole rings being 76.09 (5)°. The methyl-thio group is disordered with respect to exchange of the S and C atoms in a 0.547 (4):0.453 (4) ratio. In the crystal, C-H⋯O and C-H⋯π inter-actions connect adjacent mol-ecules into infinite layers parallel to the ab plane. The crystal packing is further stabilized by a π-π inter-action [centroid-centroid separation = 3.5187 (4) Å].
