چکیده
The title compound, C(11)H(9)N(3)O(2), exists in the E conformation with respect to the azomethane C=N bond, and has the keto form. There are two independent mol-ecules in the asymmetric unit and each of these features a slight slanting of the pyridine and furan rings, which form a dihedral angle of 14.96 (10)° in one of the mol-ecules and 5.53 (10)° in the other. The crystal structure is stabilized by N-H⋯O and N-H⋯N hydrogen bonds, weak C-H⋯O and C-H⋯N hydrogen bonds and C-H⋯π inter-actions and π-π inter-actions [shortest centroid-centroid distance = 3.7864 (15) Å].
