Secondary interactions in 1-iodo-3-nitrobenzene and 1-iodo-3,5-dinitrobenzene

K. Merz

Abstract: The crystal packing of 1-iodo-3-nitrobenzene, C₆H₄INO₂, is formed by planar molecules which are linked by II and NO₂NO₂ interactions. In the case of 1-iodo-3,5-dinitrobenzene, C₆H₃IN₂O₄, the NO₂ groups are not exactly coplanar with the benzene ring and the molecules form sheets linked by NO₂NO₂ interactions. In contrast with 4-iodonitrobenzene, the crystal structures of both title compounds do not form highly symmetrical INO₂ intermolecular interactions.

Formula: C₆H₄INO₂ and C₆H₃IN₂O₄
