Abstract: In the molecule of the title compound, C20H16N6, the central C-C bond lies on a crystallographic inversion centre. The quinoxalidine ring is nearly planar, with a maximum deviation of 0.021 (2) Å from the mean plane. The crystal structure is stabilized by intermolecular C-HN interactions, leading to the formation of a layer-like structure, which extends along the a axis.
