N2 - Molecules of N, N'-bis(4-nitrobenzylidene) ethane-1,2-diamine, C16H14N4O4, ( I), lie across centres of inversion in space group P2(1)/n and are linked into (10 (1) over bar) sheets by a single C - H ... O hydrogen bond [ H ... O = 2.40 Angstrom, C ... O = 3.2166 ( 13) Angstrom and C - H ... O = 146degrees]; these sheets are linked into a three-dimensional array by a single aromatic pi-pi stacking interaction. Molecules of N, N'-bis(4-nitrobenzylidene) propane-1,3-diamine, C17H16N4O4, (II), lie across twofold rotation axes in space group C2/ c and are linked into chains of spiro-fused rings by a single C - H ... O hydrogen bond [ H ... O = 2.54 Angstrom, C ... O = 3.267 ( 2) Angstrom and C - H ... O = 130 degrees]; these chains are linked into sheets by a single aromatic pi-pi stacking interaction.
