Key indicators: single-crystal X-ray study; T = 294 K; mean (C-C) = 0.002 Å; R factor = 0.034; wR factor = 0.101; data-to-parameter ratio = 11.5. The title compound, C 14 H 10 N 4 O 2 , was synthesized by the reaction of hydroquinone with 2-chloropyrazine in dimethyl sulfoxide. The molecules possesses crystallographic inversion symmetry with one half-molecule in the asymmetric unit. Weak face-to-facestacking interactions are observed between the pyrazinyl rings [centroid-to-centroid distance
