Experimental

R factor = 0.049; wR factor = 0.137; data-to-parameter ratio = 15.6. In the title compound, C11H14N2O3, an intermolecular inter-action between a nitro group O atom and a neighboring benzene ring helps to stabilize the crystal structure [N centroid = 3.933 (2) Å]. No classical hydrogen bonds are observed in the crystal packing. Related literature For the biological activity of 4-(4-nitrobenzyl)morpholine derivatives, see: Lan et al. (2010); Bavetsias et al.
