Controlling the molecular arrangement of racemates through weak interactions: the synergy between π-interactions and halogen bonds

POMIDLINE HORIZONTAL ELLIPSISX and NMIDLINE HORIZONTAL ELLIPSISX halogen bonds in combination with pi-stacking interactions lead to the sorting of pi-extended R- and S-isomers. Theoretical calculations point to a positive synergistic effect between the pi-interactions and the halogen bonds to be the origin of such phenomena. As a result, enantiomeric building blocks form homoleptically connected quadrangular structures.

Halogen bonds and pi-stacking interactions lead to the sorting of pi-extended R- and S-isomers, with a positive synergistic effect between the pi-interactions and the halogen bonds being the origin of such phenomena. As a result, enantiomeric building blocks form homoleptically connected quadrangular structures.
