摘要：
In the crystal structure of the title compound, C18H11N5O2, two crystallographically independent molecules having the same composition and cis-cis conformation (arrangement of the pyridyl rings) are observed. A C-H...N hydrogen bond links the centrosymmetrically related molecules into a discrete pair [C...N = 3.462 (4) Angstrom], and the structure is stabilized further by pi-pi-stacking interactions between aromatic rings from two adjacent dimers.
