The title compound, C(25)H(14)Cl(2)N(4), crystallizes with two independent mol-ecules in the asymmetric unit. The two pyridine rings are almost coplanar, making dihedral angles of 3.2 (1) and 8.6 (1)° in the two independent mol-ecules. The dichloro-phenyl and indole rings are twisted away from the bipyridine ring by 64.32 (5) and 18.46 (4)°, respectively in the first molecule and by 51.0 (1) and 27.99 (5)°, respectively in the second molecule. The crystal packing is stabilized by C-H⋯N, C-H⋯Cl, N-H⋯N and C-H⋯π inter-actions.
