(E)-N,N'-Bis[2-(5-bromo-1H-indol-3-yl)eth-yl]-N,N'-(but-2-ene-1,4-di-yl)bis-(4-methyl-benzene-sulfonamide).
In the title compound, C(38)H(38)Br(2)N(4)O(4)S(2), there is a crystallographic inversion center located at the mid-point of the alkene bond. The dihedral angle between the aromatic ring systems in the asymmetric unit is 87.69 (19)°. In the crystal, adjacent mol-ecules are linked by pairs of N-H⋯O hydrogen bonds, generating R(2) (2)(16) loops within [1[Formula: see text]0] chains. Short Br⋯Br contacts [3.6148 (9) Å] are observed between adjacent mol-ecules.
