Abstract

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).
