In both ( E , E )‐ N , N ′‐bis(4‐nitrobenzylidene)butane‐1,4‐diamine, C 18 H 18 N 4 O 4 , (III), and ( E , E )‐ N , N ′‐bis(4‐nitrobenzylidene)hexane‐1,6‐diamine, C 20 H 22 N 4 O 4 , (IV), the molecules lie across centres of inversion in space groups P and P 2 1 / c , respectively. In (III), the three‐dimensional supramolecular structure is built from π‐stacked chains of edge‐fused R 2 2 (30) rings, while in (IV), chains of edge‐fused R 2 2 (38) rings are linked by dipolar nitro–nitro interactions.
