Abstract: In the title compound, C17H14N2O6, the conformation about the C=C double bond [1.345(2)Å] is E, with the ketone moiety almost coplanar [C-C-C-C torsion angle = 9.5(2)°] along with the phenyl ring [C-C-C-C = 5.9(2)°]. The aromatic rings are almost perpendicular to each other [dihedral angle = 86.66(7)°]. The 4-nitro moiety is approximately coplanar with the benzene ring to which it is attached [O-N-C-C = 4.2(2)°], whereas the one in the ortho position is twisted [O-N-C-C = 138.28(13)°]. The molecules associate via C-H⋯O interactions, involving both O atoms from the 2-nitro group, to form a helical supramolecular chain along [010]. Nitro-nitro N⋯O interactions [2.8461(19)Å] connect the chains into layers that stack along [001].
