Abstract: There are two molecules in the asymmetric unit of the title compound, C₁₉H₁₂N₄. One is almost planar [dihedral angle between the fused-ring system and the phenyl ring = 2.16 (13)°] and one is somewhat twisted [dihedral angle = 13.30 (14)°]. In the crystal, the molecules are linked by N-HN hydrogen bonds to result in chains.
