Abstract:The title compound, C26H15BrN4O3·C2H6OS, contains five rings. The indole unit is essentially planar [maximum deviation = 0.0067 (1) Å for the N atom]. The central pyrrole ring makes dihedral angles of 44.1 (2) and 51.3 (2)° with the pendant indole ring system and the nitrobenzene ring, respectively. The benzene ring is inclined with the central pyrrole ring by 51.9 (3)°. In the crystal, N—H...O hydrogen-bonding interactions between aromatic-H-atom donors and sulfoxide-O-atom acceptors result in the formation o… Show more
