The title compound, C18H8Cl4N4, exists in a cis configuration with respect to the bridging C C bond. The two essentially planar quinoxaline ring systems [maximum deviations = 0.012 (1) and 0.022 (1) angstrom] are inclined at an angle of 59.84 (3). In the crystal, adjacent molecules are linked into chains propagating along [001] via intermolecular C-H center dot center dot center dot N hydrogen bonds. Weak intermolecular pi-pi [centroid-centroid distance = 3.6029 (7)degrees] and C-H center dot center dot center dot pi interactions are also observed.
