Molecules of 2-iodobenzaldehyde 4-nitrophenylhydrazone, C(13)H(10)IN(3)O(2), are effectively planar and are linked by an N-H...O hydrogen bond [H...O = 2.04 A, N.O = 2.905 (6) A and N-H...O = 166 degrees ] and a two-centre iodo-nitro interaction [I...O = 3.361 (4) A] into a chain of edge-fused R(3)(3)(18) rings. There are no direction-specific interactions between adjacent chains. Molecules of 2-iodobenzaldehyde 2,4-dinitrophenylhydrazone, C(13)H(9)IN(4)O(4), 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.

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.
