Molecules of 1,3‐diamino‐4‐nitrobenzene, C 6 H 7 N 3 O 2 , are linked by N—H⃛O hydrogen bonds [N⃛O 2.964 (2) and 3.021 (2) Å; N—H⃛O 155 and 149°] into (4,4) nets. In 3,5‐dinitroaniline, C 6 H 5 N 3 O 4 , where Z ′ = 2, the molecules are linked by three N—H⃛O hydrogen bonds [N⃛O 3.344 (2)–3.433 (2) Å and N—H⃛O 150–167°] into deeply puckered nets, each of which is interwoven with its two immediate neighbours.
