  "abstract": "The title cocrystal C10H6N4·C9H5N, crystalizes in the monoclinic space group Pna21 with two mol-ecules of each component in the asymmetric unit. The extended structure features four unique sp-C-H⋯N inter-actions between components that form zigzag hydrogen-bonded chains along the a-axis direction. Complementary pyridine and pyrimidine C-H⋯N bonds along the b-axis direction result in the formation of planar two-dimensional sheets. A Hirshfeld surface analysis and calculation of inter-mol-ecular inter-action energies within the crystal structure are reported.",
