5-Benzoyl-2-(5-bromo-1H-indol-3-yl)-4-(4-meth--oxy-phen-yl)-1H-pyrrole-3-carbo-nitrile

摘要

In the title compound, C27H18BrN3O, the indole and central pyrrole ring systems are inclined to one another by 13.15?(15)°. The carbo-nitrile group is almost coplanar with its attached pyrrole ring, the C≡N bond making a dihedral angle of 1.9?(2)° with the ring plane. The 4-meth-oxy-benzene 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, mol-ecules 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?inter-actions [inter-centroid distance = 3.614?(2)??], which leads to the formation of chains propagating in the [010] direction.
