Aniline–phenol recognition: from solution through supramolecular synthons to cocrystals
Aniline-phenol recognition is studied in the crystal engineering context in several 1:1 cocrystals that contain a closed cyclic hydrogen-bonded [⋯O-H⋯N-H⋯]2 tetramer supramolecular synthon (II). Twelve cocrystals of 3,4,5- and 2,3,4-trichlorophenol with one of eight halogenated anilines have been characterized. Ten of these cocrystals contain an extended octamer synthon that is assembled with h...
متن کاملRole of supramolecular synthons in the formation of the supramolecular architecture of molecular crystals revisited from an energetic viewpoint.
Analysis of the strengths and directionality of intermolecular interactions in the crystals containing only one type of supramolecular synthon allows the suggestion of a general classification of molecular crystals depending on type of their basic structural motifs. All crystals may be divided on four classes namely (I) crystals with isotropic packing of the building units; (II) columnar crysta...

متن کاملCrystal engineering in the aminophenols. Novel carborundum network in a supramolecular homologous series.
Molecular complexes of 4-(4-aminophenoxy)aniline with a series of diphenols are structurally homologous and adopt the carborundum III topology, which is an unprecedented network for organic solids.
متن کاملIdentifying the intermolecular hydrogen-bonding supramolecular synthons in an indomethacin-nicotinamide cocrystal by solid-state NMR.
Two-dimensional (1)H double-quantum and (14)N-(1)H & (1)H-(13)C heteronuclear magic-angle spinning (MAS) NMR spectra recorded at natural isotopic abundance identify specific intermolecular COOH···N(arom) and CH(arom)···O=C hydrogen-bonding interactions in the solid-state structure of an indomethacin-nicotinamide cocrystal, thus additionally proving cocrystal formation.
