Abstract: The title compound, C₂₈H₁₆N₂, also known as anthrazine, possesses a crystallographic center of inversion; thus half of the formula unit is crystallographically independent. The heptacyclic ring system is essentially planar. In the crystal structure, the molecular packing is characterized by a combination of a columnar stacking and a herringbone arrangement. Along the a axis, the molecules in one column form face-to-face slipped -stacks. The interplanar face-to-face distance between neighboring molecules is 3.495 (3) Å.
