In 2,6-diiodo-4-nitrophenol, C6H3I2NO3, the molecules are linked, by an O-H...O hydrogen bond and two iodo-nitro interactions, into sheets, which are further linked into a three-dimensional framework by aromatic pi-pi-stacking interactions. The molecules of 2,6-diiodo-4-nitrophenyl acetate, C8H5I2NO4, lie across a mirror plane in space group Pnma, with the acetyl group on the mirror, and they are linked by a single iodo-nitro interaction to form isolated sheets. The molecules of 2,6-diiodo-4-nitroanisole, C7H5I2NO3, are linked into isolated chains by a single two-centre iodo-nitro interaction.
