چکیده
In the crystal structure of the title compound, C(20)H(12)N(6)O(2), the mol-ecules are located on centres of inversion. The complete mol-ecule is almost planar, with a maximum deviation from the mean plane of 0.0657 (1) Å for the O atom. In the crystal, mol-ecules are stacked into columns elongated in the a axis direction. The centroid-centroid distances between the aromatic rings of the mol-ecules within the columns are 3.6406 (1) and 3.6287 (2) Å. Mol-ecules are additionally connected via weak inter-molecular C-H⋯N hydrogen bonding.
