摘要: Cocrystallization of N,N′-diaryloxalamides with pentafluorophenol (pfp) leads to 1:2 molecular complexes, which were characterized by X-ray crystallography. The non-planar oxalamide molecules and pfp assemble into polymeric tapes use the N–H⋯O O–H⋯O hydrogen bonds phenyl–perfluorophenyl interactions, whereas adopting planar conformations form flat trimers held together intermolecular creating two 7-membered rings.
