Halogen bonding and hydrogen bonding coexist in driving self-assembly process

A new class supramolecular architecture of 1,1,3,3-tetra-oxo-2-bromo-4,4,5,5,6,6-hexafluoro-1,3-dithiacyclohexane 1 and 2-methylpyrazine has been assembled through both hydrogen bonding and halogen bonding. However, stronger or weaker bases or electron donors such as pyrazine and N,N,N',N'-tetramethylenediamine (TMEDA) failed to give the corresponding supramolecule.
