چکیده
The crystal structure of the title Schiff base compound, C(16)H(16)N(2)O(3), is characterized by chains of mol-ecules linked by inter-molecular N-H⋯O hydrogen bonds running along the c axis. Further stabilization is provided by weak C-H⋯O contacts. The dihedral angle between the aromatic rings is 38.31 (7)°.
