title: Hydrogen bonding in substituted nitroanilines: isolated nets in 1,3-diamino-4-nitrobenzene and continuously interwoven nets in 3,5-dinitroaniline.
abstract: Molecules of 1,3-diamino-4-nitrobenzene, C(6)H(7)N(3)O(2), are linked by N-H.O hydrogen bonds [N.O 2.964 (2) and 3.021 (2) A; N-H.O 155 and 149 degrees] 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-H.O hydrogen bonds [N.O 3.344 (2)-3.433 (2) A and N-H.O 150-167 degrees] into deeply puckered nets, each of which is interwoven with its two immediate neighbours.
