5-Benzoyl-2-(5-bromo-1H-indol-3-yl)-4-(4-methoxyphenyl)-1H-pyrrole-3-carbonitrile

In the title compound, C27H18BrN3O, the indole and central pyrrole ring systems are inclined to one another by 13.15 (15)°. The carbonitrile group is almost coplanar with its attached pyrrole ring, the C[triple-bond]N bond making a dihedral angle of 1.9 (2)° with the ring plane. The 4-methoxybenzene ring and the benzoyl ring are inclined to the central pyrrole ring by 55.1 (2) and 51.5 (2)°, respectively. The dihedral angle between these two benzene rings is 37.68 (17)°. In the crystal, molecules are linked by pairs of N—H...N hydrogen bonds, forming inversion dimers with an R22(16) ring motif. The dimers are linked by offset π–π interactions [intercentroid distance = 3.614 (2) Å], which leads to the formation of chains propagating in the [010] direction.
