Molecules of 1,3-diamino-4-nitrobenzene, C6H7N3O2, are linked by N-H . . .O hydrogen bonds [N . . .O 2.964 (2) and 3.021 (2) Angstrom; N-H . . .O 155 and 149 degrees] into (4,4) nets. In 3,5-dinitroaniline, C6H5N3O4, where Z' = 2, the molecules are linked by three N-H . . .O hydrogen bonds [N . . .O 3.344 (2)-3.433 (2) Angstrom and N-H . . .O 150-167 degrees] into deeply puckered nets, each of which is interwoven with its two immediate neighbours.
