Abstract

The 21 non-H atoms of the title compound, C₁₅H₁₀Cl₂N₄, are almost planar (r.m.s. deviation = 0.032 Å); the conformation about the N=C bond [1.277 (6) Å] is E. In the crystal, zigzag supra­molecular chains along the c axis (glide symmetry) are formed via N-HN hydrogen bonds. These associate along the b axis by – inter­actions between the fused and terminal benzene rings [inter­centroid distance = 3.602 (3) Å] so that layers form in the bc plane.
