A partial view of the molecular packing in (II). Dotted lines indicate the intermolecular distances between the N atoms of the nitro groups and the O atoms of the ethoxy groups [O6i⋯N1ii = 3.392 (9) Å and N2i⋯ O3ii = 3.427 (9) Å; symmetry codes: (i) −x + 1, −y + 1, z + ; (ii) −x + 1, −y + 1, z − ]. |
