✦ Synopsis

The title compound, C 16 H 15 N 1 O 5 , is a -ketoether derivative, closely related to natural 8.4 H -oxyneolignans, which are of interest because of their antiprotozoal activity. The nitro group is not coplanar with the aromatic ring, as is shown by a torsion angle of 49.4 (3) . The molecules are connected in the crystal structure by two non-classical intermolecular hydrogen bonds with CÁ Á ÁO distances of 3.363 (3) and 3.274 (2) A Ê ; repetition of these hydrogen bonds leads to the formation of sheets of molecules parallel to the (001) plane.
