Non-Covalent Interactions Involved in the Crystal Structure of Proton-Transfer Compounds of Saccharinate Anion and Different Cations

Abstract

The synthesis and self-assembly of the proton-transfer compounds 4 and 5 of saccharin and nitrogen-containing aromatic derivatives were reported and discussed in terms of crystal engineering and supramolecular chemistry. Both compounds contain cationic and anionic fragments interacting through hydrogen bonding patterns to produce ionic supramolecular heterosynthon.
