In the title compound, C(25)H(16)N(4), the fused ring system is essentially planar [maximum deviation = 0.1012 (15) Å]. The imidazole ring makes dihedral angles of 77.41 (8) and 56.26 (8)° with the phenyl rings attached to nitro-gen and carbon, respectively. The dihedral angle between the two phenyl rings is 65.50 (8)°. Weak C-H⋯π inter-actions are found in the crystal structure.
