In the title compound, C24H14BrN3S, the dihedral angles between the planes of the pyridine ring and the pendant thio­phene ring, the indole ring system (r.m.s. deviation = 0.022 Å) and the bromo­benzene ring are 9.37 (17), 21.90 (12) and 69.01 (15)°, respectively. The approximate coplanarity of the central ring and the indole ring system is supported by two intra­molecular C—H...N inter­actions. In the crystal, inversion dimers linked by pairs of N—H...N hydrogen bonds generate R22(16) loops and the dimers are linked by C—H...π and aromatic π–π stacking [shortest centroid–centroid separation = 3.729 (3) Å] into a three-dimensional network.
