Abstract: The title compound, C20H10Cl2N2, has crystallographic twofold rotational symmetry [maximum deviation from the least-squares plane = 0.038 (1) Å]. In the crystal, weak [pi]-[pi] ring stacking interactions occur down the a-axis direction [minimum centroid-centroid separation = 3.7163 (8) Å].
