The quest for understanding crystal structures using supramolecular cluster demarcation has been applied to various uncharged compounds, and, more recently, to charged compounds. So, what would be the supramolecular behavior of mesoionic compounds?
The supramolecular organization of organic salts has been widely researched, revealing recurring patterns in crystalline lattices that describe their supramolecular properties.
Variations in solvents, flexibility, and the presence/absence of amide–amide interactions can modulate the competition between amide-containing isoxazole polymorphs.
Crystallization mechanisms were proposed to investigate hydrogen bond and aromatic donor–acceptor interactions in a series of phenyl–perfluorophenyl amides. The modulation of NH⋯O
C bonds and aryl complementarity drove a new cocrystal growth.
The current investigation provides energetic and contact surface data on intermolecular interactions, correlates theoretical data with experimental data and suggests a proposal for nucleation for halogenated aryl amides.
