organic compounds
In the title compound, C18H14N2O4, the torsion angles of the single bonds between the hexatriene chain and 4-nitrophenyl rings are 18.0 (2) and −0.7 (2)°. The molecules are linked weakly via intermolecular C—HO hydrogen bonds to form sheets. These sheets are linked further by NO dipole interactions between the nitro groups and aromatic π–π stacking interactions, to form a three-dimensional framework.
