Article abstract of DOI:10.1107/S0108270193014477

In the title compound, C15H13NO4, the two planar nitrophenyl and benzyloxy groups are inclined at 152.3(2) deg.The torsion angle about the central C-O bond is 177.5(5) deg, giving an extended C-C-O-C chain.The nitro group is twisted out of the plane of the phenyl ring by 28.4(3) deg to diminish steric hindrance; O atoms of the nitro and benzyloxy groups are separated by only 2.625(7) Angstroem.The dihedral angles between the epoxy ring and the two aromatic rings are 98.3(3) and 102.6(3) deg.There is a possible C-H...O intermolecular interaction.
