Nine isomeric nitrobenzylidene-iodoanilines: interplay of C—H...O hydrogen bonds, iodo...nitro interactions and aromatic π...π stacking interactions

In crystalline nitrobenzylidene-iodoanilines, isolated molecules may occur, or the molecules may be linked by some combination of C—H...O hydrogen bonds, iodo...nitro interactions and aromatic π...π stacking interactions, so giving overall supramolecular structures in zero, one, two or three dimensions.
