Halogen bonding in fluorine: experimental charge density study on intermolecular F⋯F and F⋯S donor–acceptor contacts

Abstract

The enigmatic type II C-F···F-C and C-F···S-C interactions in pentafluorophenyl 2,2'-bithiazole are shown to be realistic "σ-hole" interactions based on high resolution X-ray charge density analysis.
