A chain of edge-fused rings generated by the combination of an N-H·O hydrogen bond and an iodo-nitro interaction in 2-iodobenzaldehyde 4-nitrophenylhydrazone versus disordered and effectively isolated molecules in 2-iodobenzaldehyde 2,4-dinitrophenylhydrazone

Molecules of 2-iodobenzaldehyde 4-mitrophenylhydrazone. C13H10IN3O2, are effectively planar and are linked by an N-H...O hydrogen both [H...O = 2.04 A, N...O = 2.095 (6) A and N-H...O = 166°] and a two-centre iodonitro interaction [I...O = 3.361 (4) A] into a chain of edge-fused R33(18) rings. There are no direction-specific interactions between adjacent chains. Molecules of 2-iodobenzaldehyde 2.4-dinitrophenylhydrazone, C13H9IN4O4, are disordered over two orientations with occupancies of 0.681 (5) and 0.319 (5). In the major orientation, there are no direction-specific intermolecular interactions, while for the minor form, a single C-H...O hydrogen bond generates centrosymmetric dimers.
