Abstract: In the title compound, C14H8Cl2N4O2, the pyrazine rings are orthogonal to the benzene ring, making dihedral angles of 88.42 (8) and 89.22 (8)°. The Cl atoms attached to the pyrazine rings deviate by -0.0597 (5) and 0.0009 (5) Å from the ring plane. The crystal structure features C-HN hydrogen bonds.
