1. Three isomeric (E)-nitrobenzaldehyde nitrophenylhydrazones: chains of rings in isomorphous (E)-2-nitrobenzaldehyde 3-nitrophenylhydrazone and (E)-3-nitrobenzaldehyde 2-nitrophenylhydrazone, and centrosymmetric dimers in (E)-4-nitrobenzaldehyde 2-nitrophenylhydrazone

Abstract

The isomeric compounds (E)-2-nitro­benzaldehyde 3-nitro­phenyl­hydrazone and (E)-3-nitro­benzaldehyde 2-nitro­phenyl­hydrazone, both C13H10N4O4, are isomorphous and effectively isostructural, and in both, the mol­ecules are disordered across centres of inversion in the space group P21/c. The mol­ecules are linked into complex chains of rings by N—H⋯O and C—H⋯O hydrogen bonds. In the isomeric compound (E)-4-nitro­benzaldehyde 2-nitro­phenyl­hydrazone, the fully ordered mol­ecules are linked by N—H⋯O hydrogen bonds into centrosymmetric dimers.

Abstract

Molecules of 2-nitrobenzaldehyde hydrazone, C7H7N3O2, where Z' = 2, are linked by two N-H...N hydrogen bonds into isolated dimers, whereas in the isomeric 3-nitrobenzaldehyde hydrazone, where Z' = 1, the molecules are linked by one N-H...O hydrogen bond and one N-H...N hydrogen bond into a three-dimensional framework structure.
