چکیده
The title Schiff base compound, C(14)H(12)N(4)O(3), displays an E conformation with respect to the C=N double bond [1.268 (3) Å]. The dihedral angle between the benzene rings is 3.2 (5)°, consistent with an essentially planar mol-ecule. In the crystal, N-H⋯O and N-H⋯N hydrogen bonds, as well as C-H⋯O inter-actions, link the mol-ecules into layers that stack along the c axis.
