Abstract

In the title compound, C₁₈H₁₈N₄O₆, the piperazine ring adopts a chair conformation, the amidic N atom is planar (sum of angles = 360°) and the non-amidic N atom is pyramidal (343°). There are no hydrogen bonds of any kind in the crystal, but the mol-ecules are linked by two independent π(nitro-benzene)⋯π(meth-oxy-benzene) stacking inter-actions to form π-stacked sheets with inter-centroid separations of 3.8444 (12) and 3.9197 (12) Å.

Keywords: crystal; molecular conformation; synthesis; π–π stacking.
