The title compound, C12H6N4, crystallizes with four independent molecules (A, B, C and D) in the asymmetric unit. The dihedral angles between the two pyridine rings in each molecule are 25.25 (8)° in A, 5.51 (9)° in B, 11.11 (9)° in C and 16.24 (8)° in D. In the crystal, molecules A and B are linked by C—H...N hydrogen bonds to form layers extending parallel to the ab plane, while molecules C and D are linked by C—H...N hydrogen bonds forming –C–D–C–D– chains propagating along the b-axis direction. The layers and the chains are stacked alternately along the c axis through offset π–π and C[triple-bond]N...π [N-to-pyridine-centroid distance = 3.882 (2) Å] interactions, resulting in the formation of a supramolecular framework.
