Abstract

The 21 non-H atoms of the title compound, C15H10Cl2N4, are almost planar (r.m.s. deviation = 0.032Å); 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 π-π interactions between the fused and terminal benzene rings [intercentroid distance = 3.602(3)Å] so that layers form in the bc plane.
