The molecules of 2‐nitrobenzaldehyde isonicotinoylhydrazone, C 13 H 10 N 4 O 3 , (I), are linked into a three‐dimensional framework by a combination of one N—H⋯N and three C—H⋯O hydrogen bonds. In the isomeric compound 3‐nitrobenzaldehyde isonicotinoylhydrazone, (II), the molecules are linked into complex sheets by a combination of three hydrogen bonds, one each of the N—H⋯N, C—H⋯N and C—H⋯O types. The molecules of the third isomer, namely 4‐nitrobenzaldehyde isonicotinoylhydrazone, (III), are linked into bilayers by a combination of one N—H⋯N, one C—H⋯N and two C—H⋯O hydrogen bonds. 2,4‐Dinitrobenzaldehyde isonicotinoylhydrazone, (IV), crystallizes as a stoichiometric monohydrate, C 13 H 9 N 5 O 5 ·H 2 O, and the molecular components are linked into a three‐dimensional framework by a combination of O—H⋯O, O—H⋯N, N—H⋯O and three independent C—H⋯O hydrogen bonds.
