Abstract
The molecules of 2-nitrobenzaldehyde isonicotinoylhydrazone, C13H10N4O3, (I), are linked into a three-dimensional framework by a combination of one N-H
N and three C-HO 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-HN, C-HN and C-HO types. The molecules of the third isomer, namely 4-nitrobenzaldehyde isonicotinoylhydrazone, (III), are linked into bilayers by a combination of one N-HN, one C-HN and two C-HO hydrogen bonds. 2,4-Dinitrobenzaldehyde isonicotinoylhydrazone, (IV), crystallizes as a stoichiometric monohydrate, C13H9N5O5·H2O, and the molecular components are linked into a three-dimensional framework by a combination of O-HO, O-HN, N-HO and three independent C-HO hydrogen bonds.
