摘要: Molecular tapes mediated via strong O–H⋯N hydrogen bonds and weak C–I⋯O interactions are present in complexes of 4-nitrobenzoic acid·4-iodopyridine 3,5-dinitrobenzoic acid·4-iodopyridine. Crystal structure 4-nitrobenzamide·4-iodobenzamide has amide dimer tape iodo⋯nitro interaction orthogonal directions. There is good structural insulation the bonding halogen domains these crystal structures. However, less polarizable bromine chlorine atoms show cross-pairing that predictable. These preliminary results both carboxylic acid⋯pyridine heterosynthons may be simultaneously exploited for design.
