Deskripsi
In the title compound, C16H10N4O4, the two pyridine rings are twisted by 44.41 (2)° and the ester groups form dihedral angles of 48.77 (4) and 45.75 (2)° with the corresponding pyridine rings. The crystal structure is stabilized by intermolecular C—H...O hydrogen bonds and π–π stacking interactions between the pyridine rings [centroid-to-centroid distance 3.797 (2) Å].
