(E)-N,N′-Bis[2-(5-bromo-1H-indol-3-yl)ethyl]-N,N′-(but-2-ene-1,4-diyl)bis(4-methylbenzenesulfonamide)

Abstract

In the title compound, C38H38Br2N4O4S2, 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 molecules are linked by pairs of N—H...O hydrogen bonds, generating R22(16) loops within [1overline{1}0] chains. Short Br...Br contacts [3.6148 (9) Å] are observed between adjacent molecules.
