The asymmetric unit of the title compound, C16H14N4O4, contains one half-molecule of (nitrophenyl)ethanimine and the complete molecule is generated by a crystallographic inversion centre. The molecule has an E conformation with respect to each C=N double bond. The central C=N—N=C plane is twisted from the benzene rings with a dihedral angle of 24.76 (11)°. In the crystal, C—H⋯O interactions link the molecules to form sheets that lie parallel to (10-4).
