2,6-Diiodo-4-nitrophenol, 2,6-diiodo-4-nitrophenyl acetate and 2,6-diiodo-4-nitroanisole: interplay of hydrogen bonds, iodo-nitro interactions and aromatic --stacking interactions to give supramolecular structures in one, two and three dimensions

Abstract: In 2,6-diiodo-4-nitrophenol, C₆H₃I₂NO₃, the molecules are linked, by an O-HO hydrogen bond and two iodo-nitro interactions, into sheets, which are further linked into a three-dimensional framework by aromatic [bold 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.

Formula: C₆H₃I₂NO₃, C₈H₅I₂NO₄ and C₇H₅I₂NO₃
