Abstract

A Cambridge Structural Database study was undertaken to investigate the role of C-X…π interactions (X=F, Cl, Br, I) in conformational and crystal engineering control in organic crystal structures. This analysis reveals that organic fluorine has a greater propensity for the formation of such interactions rather than accepting hydrogen bonds. These results also compare well with the recently analyzed C-H…π interactions and depict the orientational dependency and the control of crystal packing in organic molecules.
